Question

A pedometer indicates a person walked 4500.0 steps in 20.0 minutes. Each step is 0.75 m long.What is the speed in meters/second?

Karl P. · Accepted Answer

Assuming constant speed, it would be 2.8 m/s.

20 minutes = 1200 seconds.

Assuming each step is 0.75 meters, and you have 4500 steps, you do 4500 * 0.75 = 3375 meters.

3375 meters / 1200 seconds = 2.8 m/s.
