Question

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

d

Explanation:

Answer 2

3 ft/s * (3600 s/h) * (1 mi)/(5280 ft) = 45/22 mi/h ≈ 2.045 mi/h

Morris's speed is about 50 mi/h -2.045 mi/h = 47.955 mi/h ≈ 48 mi/h

The 4th selection is appropriate.
