suppose a ferris wheel is moving at a constant rate of 8 inches per second. if the diameter of the wheel is 60 feet, how long will it take the ferris wheel to make a complete revolution?

Answer 1

pi d = 3.14 * 60 = 188.4 feet in one rev
8 in = 8/12 = 2/3 foot = 0.667 feet per second
188.4 feet * 1 second / .667 foot = 282 seconds
which is about 4.7 minutes
