(1 mile = 5280ft)

Question

How many revolutions will a car wheel of 30in make as the car travels 1 mile?

Answer 1

You forgot to say whether the car wheel's diameter or radius = 30 inches.

Fix that!

Then calculate the Circumference of the wheel in ft.

Divide the above Circumference (ft) into 5,280 ft to get # of revolutions.
