### What is your walking stride length?

Today in class we learned about proportional statement.  In each statement you needed 2 equivalent fractions (ratios).  You showed how to prove they were equivalent 2 different ways.

Using the information from today's class please figure out the length of just one stride or stride length.
Remember that there are 80 squares in the sidewalk, each square is 145 cm  and the total sidewalk is 11600 cm.

You counted your number of steps or strides, you know how long the sidewalk is so.... how far is one stride or your stride length ?

Please leave your answer in the comments below this blog post and in your notebook:)

I took 170 steps and it equals 11600cm. My 1 step is equal to unknown. So take the 11600 and divide it by 170 and it equals 68cm. Another way is going 170 divided by 170 equals 1 and 11600 divided by 170 equals 68. Now 1 step is equal to 68cm. Here it is in math form.

170 steps = 11600cm

1 step = ?

÷170
170 1
----- = -----
11600 68
÷170

1 step = 68cm

I took 172 steps and it all equals to 11600cm. My first step is unknown. So I take 11600 and divide it by 172 and it equals 86. Then I divide 172 and divide it by 172 and it equals 1. So 1 step equals to 86cm.

172 steps= 11600

Each step= ?

172÷172= 1
172÷11600=86

Each step= 86cm

I took 171 steps and equals to 116000cm.My each step is unknown.So I take 11600cm and divide it by 171 and equals to 61cm.Then I divide 171 by 171 equals 1 and 11600 divided by 170 equals to 61cm. Now each of my step is 61cm.

171 steps = 11600

1 step = ?
171 divided by 171 = 1
171 divided by 11600 = 61
each step is 61cm.

~What is your Walking Stride Length

My walking stride length is 58 cm. I got this because it took me 200 steps to go from one x to the other. Since we have to find out how long one step is, that is unknown for now. In order for me to answer this, I used the distance between the 2 x's and how many steps I took. So I divided 11 600 by 200 and received an answer of 58cm, so this fills in the unknown number. To make sure, I divided 200 divided by 200 = 1 and 11 600 divided by 200 = 58.

11 600 = 200 steps

1 step = unknown

200
÷
200 1 steps
------ = -- = -----
11 600 58 cm

The total steps I took was 181 steps which is equivalent to 11600cm. The length of one step is still unknown. So I solved this by using the total lengths which was 11600cm and 181. I started by: 11600 ÷ 181 which equaled to 64cm. To make sure of my answer, I did 181÷181=1, then 11600÷181=64.

1600cm = 181 steps
unknown (?) = 1 step

1600 181 cm
----- = ----- = -----
64 1 steps

Walking Stride Length = 64cm

I took 175 steps. 1 step is unknown at the moment. In order for me to find the answer, I divided the distance between the 2 green x's(11600cm), by the number of steps I took,(175) which equals 66cm.(11600÷175=66cm) To make sure, I divided 175 by 175 = 1 and divided 11600 by 175 = 66cm.

11600 = 175 steps
1 step = unknown?

÷175
175 1 step

I took 170 steps and it equals to 11600cm. My first step is unknown. So what I did was I take 11600 divided it by 170 and equals to 68cm. Then I divided 170 by 170 equals 1 and 11600 divided by 170 is equals to 68cm. So that means each of my steps is 68cm.

170 Steps= 11600cm

1st step=?

170 divided by 170=1
170 divided by 11600=68cm

Each step is 68cm

My partner and I measured green x to green x and we got 12160cm. We got the answer by measuring one cement using 30 cm ruler. Each cement contains 152 centimeters. After that, we counted how many cements are there between the 2 green Xs. There are 80 cements. Some cements are longer than the others, so we just doudle the cement. We multiplied the number of the cements, wich is 80 to how long the cements are, 152 cm.
So. . 80 x 152 is equal to 12160. And thats how we got the answer. The tools we used are calculator, 3 30cm rulers and our brains.

It took me 165 steps to get 1 x to the other and it equals to 11600cm. My stride length is unknown. What I have to do is take my 11600cm and divide it by 165, it equals to = 70cm.

164 steps = 11600cm
1 step = ?cm
164 ÷ 11600cm = 70cm
1 step = 70cm

i took 186 steps which is 11600 but i dont know what 1 step is. so i divde 11600 by 186 which is 63cm. Then i divde 186 by 186 which is 1 so it means 1 step is 63 cm

186 steps is 11600

1 step is unknown

11600 divded by 186 is 63cm

186 divded by 186 is 1

1 step is 63cm

~What is your Walking Stride Length~

I took was 203 steps which is equivalent to 11600cm. The length of one step is still unknown. I started by: 11600 ÷ 181 which is approximately to 57 cm. To make sure of my answer, I did 181 ÷1 81 = 1, then 11600 ÷ 181 = 64.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1600cm = 181 steps
(?) = 1 step

203 ÷ 203 = 1

11 600 ÷ 203 = 57

Walking Stride Length = 57 cm

I took 154 steps for my walking stride and it equals 14080cm. So I take 14080 divivde it by 154 and it equals 91cm. For my running stride I got 107 steps and then divide it by 14080 and it equals 135cm. Then my sprinting stride I got 70 steps then I divide it by 14080 and I got 201.

154 divided by 154 =1cm
14080 divided by 154 =91cm
1 stride =91cm

107 divided by 107 =1cm
14080 divided by 107=131cm
1 stride=131cm

70 divided by 70 =1cm
14080 divided by 70= 201cm
1 stride =201cm

I measured how many strides it would take me to do 1 block. It took me about 2.3 strides. I then multiplied 2.3 by 80, which is equal to 184 strides. I still don't know what my walking stride is. The sidewalk is equal to 13760cm. To figure out my walking stride divide 13760cm by 184. My 1 stride is 75cm.

1 stride=?
1 block= 2.3 strides

2.3x80= 184 strides
13760÷184=74.7 (75)

1 stride = 75 cm
It took me 200 strides when jogging. Take 13760cm and divide it by 200. You get 69 cm. 1 jogging stride is equal to 69 cm.

I took 163 steps and it equals 14080. So im gonna divide 14080 by 163 and that equals 86. Another way of showing this is 163 divided by 163= 1 and 14080 divided by 163 =86. So each step i take is 86cm.

168 steps =14080

163÷163=1
163÷14080=86

Each step =68cm

I figured out my walking stride and it equaled 64. I found this out by knowing that I took 179 steps from the two x's on each side. Right now, how long my step is, is unknown. I used the distance of the two x's which was 11, 600 and I divided that by my 179 steps. My answer to that which fills the variable is 64. Then, I had to make sure so I divided 179 ÷ 179 =1 and 11, 600 ÷ 179 =64.

11,600 steps = 179 steps

1 step = variable

179 ÷ 179 =1

11,600 ÷ 179 =64cm

It took me 136 steps from one X to the other.

cm/steps
11600cm/136steps=Xcm/1step

I solved the X by cross multiplying 11,600x1 and 136x(X)
11,600=136X
X=85.29cm

I took 168 steps to walk between the two x's, and it it equaled to 11600cm. My first step wasnt known yet. So I took 11600cm and divided it by 168 and got the answer of 69cm. When I double checked I divided 168 by 168 and it equaled to 1. So my walking stride length was 69cm. Here it is on math form.

11600 = 168 steps
1 step = unknown?

÷168
168 1 step
----- = --- = ----
11600 69cm
÷168

I found out mt walking stride and its 87. I found out my answer by walking to each of the x's and i got 161 steps. My step is unknown right now. I used the distance between the two x's which is 14080 and then i divided it by how many steps i took which is 161, which equaled to 87(that is my walking stride). To check my answer i divided 161 by 161 and the answer is 1 and then after i did 14080 divided by 161 which is 87.
Here below is in math form.

161 steps= 14080cm

161÷161=1
161÷14080=87

my walking stide= 87.

I took 170 steps which equals to 11600cm. 1 step is equal to unknown. So what I did was I divided 11600 I got 68cm and a bunch of other decimals so I just used 68cm.

170 Steps= 11600cm

1 Step= unknown

170 ÷ 1= 1

170 ÷ 11600 = 68

so each step is 68cm

Answers:
One stride walking: 87.45 cm
One stride jogging: 122.43 cm
One stride running: 156.44

Walking:
It took me 161 steps to walk from X to X. I used a proportion statement to answer this problem.
Information- 61 steps, 14,080 cm (length between the X's), 1 stride.
Word ration: strides (up), cm (down)
1= 161 (divide 161 to 161 and you get 1)
87.45 cm=14,080 cm (divide 14,080 to 161 and you get 87.45)

Jogging:
It took me 115 steps to jog from X to X. Using a proportion statement, this is how I got my answer.
Information- 115 steps, 14,080 cm, 1 stride.
Word ration: strides (up), cm (down)
1= 115 (divide 115 to 115 ans you get 1)
122.43 cm= 14,080 cm (divide 14,080 to 115 and you get 122.43)

Running:It took me 90 steps to walk from X to X. I used a proportion statement to answer this problem.
Information- 90 steps, 14,080 cm (length between the X's), 1 stride.
Word ration: strides (up), cm (down)
1= 90 (divide 90 to 90 and you get 1)
156.44=14,080 cm (divide 14,080 to 90 and you get 87.45)
