Suppose a car tire has a diameter of 32 inches. how many complete rotation will it make if it traveled one mile.

Question

Answer choices are 

F. 26 rotations

G. 52 rotations

H. 315 rotations

J.  630 rotations

Answer 1

1 mile is about 5280 ft = 12(5280) inches = 63360 inches

 

Divide this by the circumference of the wheel.

 

(63360 inches)/[π(32 inches)] ≅ 630 rotations
