Question

A bus travels 132 miles in 2 hours on the highway. The bus driver wants to find the average speed of the bus in feet per second. Find the average speed of the bus in feet per second using the units as a guide.

Answer 1

132 miles / 2 hours = 66 miles per hour.

1 mile = 5,280 feet

1 hour = 3600 seconds

66 x 5,280 = 348,480 feet per hour.

348,480 feet / 3600 seconds = 96.8 feet per second.
