How many revolutions will a car wheel of diameter 28 in. make over a period of half an hour if the car is traveling at 60mi/hour
I know the answer is 21,609 but I don't understand how to get it.
I've been on this problem for 30+ minutes. >.<
S= r*theta
I know the radius is 14, and half an hour is 30mi/h
I don't understand how to derive the rest. Thank you.
