Minute hand of a clock is 10 inches long.
how far does the tip of the minute hand move in 15 seconds?
I got that=5 pi

BUT What speed is it moving in miles/hr????

Assuming it does move 5 pi, convert 5 * 3.1416 = 15.7 inches to portions of a mile. Convert 15 seconds into a portion of an hour, then increase both so divisor is a complete hour.
