Using a pedometer, you walk 3000 steps in 20 minutes, so your speed is 150 steps/min. each of your steps is 0.7 m long. what is your speed? 150 steps/min=/s=/h

150 steps/min=1.75 m/s=6.36 km/h

Explanation:

First of all, we need to convert 3000 steps into meters and 20 min into seconds. We know that

1 step = 0.7 m

1 min = 60 s

so,

So, the speed is

Now we need to convert into km/h. We know that:

So, we have

So, the velocity is
