A parachutists speed during a free fall reaches 153 miles per hour. What is this speed in feet per second? at this speed, how many feet will the parachutist fall during 15 seconds of free fall? in your computations, use the fact that 1 mile is equal to 5280 feet. do not round your answer

153 miles x 5280 feet per mile = 807,840 feet per hour.

1 hour = 3600 seconds.

The speed is 807,840 feet / 3600 = 224.4 feet per second.

Distance in 15 seconds = 224.4 x 15 = 3,366 feet.
