Question

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

3600 seconds in 1 hour

3 x 3600 = 10,800

10,800 / 5280 = 2.05

50 - 2 = 48 miles per hour
