A parachutist descends 56 feet in 4 seconds. What integer represents the parachutist's change in height in feet per second?
To find the parachutist's change in height in feet per second, we can divide the descent in feet by the time in seconds:
Change in height = Descent / Time
Change in height = 56 feet / 4 seconds
Simplifying,
Change in height = 14 feet per second
The integer that represents the parachutist's change in height in feet per second is 14.
