Answer:
-140 feet
Step-by-step explanation:
The relation between speed, distance, and time can be written ...
distance = speed × time
distance = (28 ft/s)(5 s) = 140 ft
In 28 seconds, the skydiver changed position by 140 feet. Since the direction is presumed to be down (falling), the change in altitude is -140 feet.
