The radius of this fan is 1.5 feet, which means that the circumference
(2Pr) of the circle the fan makes is 3P
feet. If the fan makes 1760 revolutions in a minute, it will make
1760*60 revolutions in an hour. Multiply this product times
3P to get the number of feet the point will
travel in an hour, and then divide by 5280 to convert to miles. The
result is 60P, or choice E.
