Question

A point on a wheel moves at 33pi/4 radians per minute. How many seconds are required for the point to complete 10 revolutions?

Answer 1

Answer: the answer is "145.5" seconds

Step-by-step explanation: I took the test.

Answer 2

Revolutions per minute = (33π/4)/(2π) = 33/8 and this is 33/(8 x 60) = 33/480 revolutions per second

Ten revolutions will therefore take 10 / (33/480) = 4800/33 = 145.5 sec
