Question

If one of your strides while walking at a constant rate over a flat surface equals 0.60 yards, how many strides would it take to walk exactly one mile? 

Answer 1

1 mile = 1780 yds

1 stride = 0.60 yds

We need to convert 1 mile to strides.

Using dimensional analysis, we have...

1 mile x 1780 yds/mile x 1 stride/0.60 yds = 2966.666..... strides. The value of 0.60 yds has 2 significant figures, so our answer will be 2900 strides to walk 1 mile
