A pedestrian makes 90 steps in one minute, determine the average speed of a pedestrian

A pedestrian makes 90 steps in one minute, determine the average speed of a pedestrian, assuming a step length of 60 cm.

First, let’s find the entire distance traveled by a pedestrian who has made 90 steps. To do this, multiply the stride length by its amount:

90 steps * 60 cm = 5400 cm.

Let’s translate the resulting centimeters into meters:
5400 cm = 54 m.

And in kilometers:
54 m = 0.054 km.

Now let’s convert minutes to hours:
1 min = 1/60 h

Let’s write the formula for the average speed for a pedestrian:

u = s / t = (0.054 km) / (1/60 h) = 3.24 km / h.

Answer: 3.24 km / h.
