The radius of each wheel on a bicycle is 0.400 m. The bicycle travels a distance of 3.0 km. Assuming that the wheels do not slip, how many revolutions does each wheel make?(adsbygoogle = window.adsbygoogle || []).push({});

This problem seems so simple but none of the possible answers available seems correct.

My work

r = 0.4 m

x = 3 km = 3000 m

# of revolutions = x / [(2)(Pi)(r)] = 3000 / (2 x 3.14 x 0.4) ~119.4 m?

-------------------------

Below are the answers to choose from

8.4 × 10-4 revolutions

1.2 × 103 revolutions

Since the time of travel is not given, there is not enough information for a solution.

6.0 × 103 revolutions

2.4 × 102 revolutions
