section 5.1 problem number 78
** **
78. The radius of each wheel of a car is 15 inches. If the wheels are turning at 3 revolutions / second, how fast is the car moving? Express your answer in inches per second and in miles per hour.

The answer I came up with is 90`pi in/sec and 16.06 mph. I just want to make sure how to convert units. If I'm incorrect can you show me how to get the correct answer?

@& Note that I generally need to see your reasoning on a problem as opposed to just an answer.
The 90 pi in / sec is correct. 16 mph is certainly in the right ballpark. So this looks good.*@
