Correct Answer

Explanation


The average speed of a vehicle is calculated by dividing the total distance traveled by the total time taken.

In this case, the total distance traveled is 80 km, and the total time taken is 75 minutes, or 75/60 hours. The average speed is then 80 / (75/60) = 64 km/hr.
