Final answer:
The skydiver falls at a rate of 235 feet per second before opening the parachute, calculated by dividing the total distance of 14,100 feet by 60 seconds.
Step-by-step explanation:
The student is asking how many feet a skydiver falls per second before opening the parachute if it takes 60 seconds to fall 14,100 feet. To calculate the number of feet fallen per second, we need to divide the total distance fallen by the time it took to fall.
Feet per second = Total distance ÷ Time
Feet per second = 14,100 feet ÷ 60 seconds
Feet per second = 235 feet/second
Therefore, the skydiver falls at a rate of 235 feet per second before opening the parachute.
