Question

A parachutist's rate during a free fall reaches 99 miles per hour. What is this rate in feet per second? At this rate, how many feet will the parachutist fall during 20 seconds of free fall? In your computations, use the fact that 1 mile is equal to 5280 feet.

Answer 1

Rate = ft/s
Distance fallen in 20 sec = ft

Answer 3

first consider that there are 5280ft/mile

Answer 4

and 3600 seconds in an hour

Answer 5

so you have
\[99m/h * 5280ft/m*1hour/3600\sec\]=\[x f/s\]
