Answer:
Explanation:
A parachutists rate during a free fall reaches 153 miles per hour. To determine the rate in feets per second, we will convert hours to seconds. We will also convert the miles to feet.
1 hour = 60 × 60 = 3600 seconds.
1 mile = 5280 feets
Therefore, it will become
(153 × 5280) / 1× 3600
= 807840 /3600
= 224.4 feets per second
153 miles per hour = 224.4 feets per second
At this rate, the number of feets that the parachutists will fall during 15 seconds of free fall will be
speed × time = 224.4 × 15 = 3366 feets
