Aneesha travels at a rate of 50 miles per hour. Morris is traveling 3 feet per second less than Aneesha. Which is the best estimate of the speed Morris is traveling?

1 mile = 5,280 feet

45 miles per hour
46 miles per hour
47 miles per hour
48 miles per hour

Answer 1

Answer : 47 miles per hour
50 mph = 50*5280 ft / hour = 50*5280 / 3600 ft / sec 73.33 ft/sec so Morrius speed is 70.433 ft/sec in mph this is (70.33* 3600 )/ 5280 = 47 mph
