Question

A car travels at 36 feet/second. What is the car's speed in miles/hour? Choose the best answer.

(1 mile = 5280 feet)

Answer 1

mile per minute = 60 mph= 5280 ft/60 sec = 5280/60 ft/sec = 88 ft/sec

36 ft/sec = 36/88 x 60 mph = 9/22 x 60 = 9(30)/11 = 270/11 mph = 24 6/11 mph

= about 24.5455 mph

= 24.5454545454... mph
