The cyclist travels 5 m / s. How many full revolutions does the wheel make in 5 seconds if the circumference of this wheel is 125 cm.

To solve the problem, you first need to determine the distance that the cyclist travels in 5 seconds.
To do this, we multiply the cyclist’s speed by time.
We get:
5 * 5 = 25 meters.
We translate this distance into centimeters.
Since 1 meter is 100 centimeters, then 25 meters:
25 * 100 = 2500 centimeters.
We find the number of turnovers.
To do this, we divide the distance traveled by the cyclist in 5 seconds by the radius of the circle of his wheel.
In this case, we get:
2500/125 = 20 turns.
