Question

John's tire is 2.25 ft in diameter. If his driveway is 150 ft long, how many complete rotations will his tire have to make to travel the length of his driveway? (use 3.14 for π)

Answer 1

21 complete rotations

Explanation:

We need the circumference of the tire, which is 2.25*3.14=7.065

Then we can divide it with 150/7.065 is about 21 rotations.

So ans: 21 complete rotations.
