Answer:
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
The average velocity of the mail truck after traveling such distance is 9,275.1 miles per hour
Given'
Distance 1 = 31,500 Miles
Distance 2 = 31,713 miles
Total time taken = 6.5 hours
Average velocity = Total distance ÷ Total time
= (Distance 1 + Distance 2) ÷ Total time taken
= (31,500 + 31,713) ÷ 6.5
= 63,213 ÷ 6.5
= 9725.0769230769
Approximately, 9,275.1
Therefore, average velocity of the mail truck is 9,275.1 miles per hour
