Answer:
The police will cite you for speeding.
Explanation:
To know if the police will cite you for speeding we need to find the average speed (v):
<u>Where:</u>
x(f): is the final distance = 39 mi
x(i): is the initial distance = 0
t(f): is the final time = 53 min = 0.88 h
t(i): is the initial time = 17 min = 0.28 h
Hence, the average speed is:
Therefore, since the limit speed is 60 mph and your speed is 65 mph, the police will cite you for speeding.
I hope it helps you!
