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;
  = [tex]\frac{617760}{3600}[/tex]
  =  171.6 feet/second
2. In 10 second of free fall,
    speed = [tex]\frac{distance}{time}[/tex]
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.
