Step-by-step explanation:

Average speed = total distance / total time taken

Average speed is the total distance traveled divided by the total time taken

The carrier first odometer route is

d_1 = 31,500 miles

On return of the truck, the odometer reads

d_2 = 31,713 miles

The total time taken is 6.5 hours on return

Then,

Average Speed = total distance / total time.

A. V = (d_1 + d_2) / t

A. V = (31,500 + 31713) / 6.5

A. V = 63213 / 6.5

A. V = 9725.1 mile per hour

A. V = 9725.1 mph
