Answer:
1. rate = 171.6 feet/second
2. 1716 feet
Step-by-step explanation:
1. To convert from miles per hour to feet per second,
1 mile = 5280 feet
117 miles = 617760 feet
1 hour = 3600 seconds
Thus the rate in feet per second will be;
=
= 171.6 feet/second
2. In 10 second of free fall,
speed =
distance = speed x time
= 171.6 feet/second x 10 second
= 1716 feet
The parachutist would fall 1716 feet in 10 seconds of free fall.
