The answer is on the paper
Answer:
Option C
Step-by-step explanation:
The given function is:
.
.
.
The average rate of change of this function on the interval t=3 to t=5 is given by:


Since the average rate of change is negative on the interval 3-5 seconds, it means the ball is moving downwards at an average rate of 48 feet per second.
The correct choice is C.
