Question

A car starts from rest travels on a straight road and its wheel rotates 500 rotations in 15 s. If the diameter of a car’s wheel is 60 cm, calculate the distance traveled by the car.

Answer 1

Solution. After 500 revolutions, the distance traveled is

$$d=\pi\times d\times 500$$

where d=0.6m is diameter of a car’s wheel. As result get

$d=\pi\times 0.6\times 500 \approx$ 942m

Answer. 942m.
