Question

A rural mail carrier logged the mileage on the odometer at the start of the mail route as 31,500 miles. After 6.5 hours, the carrier returned the truck and recorded the mileage at 31,713 miles. What was the average velocity of the mail truck? Explain your reasoning.

Answer 1

Answer:
`32.77\ mi/hr`

Step-by-step explanation:

Given

Initially Reading on the odometer is
`31,500\ miles`

Final reading on the odometer is
`31,713\ miles`

Time taken is
`t=6.5\ hr`

average velocity
`=\frac{\text{Displacement}}{\text{time}}`

`v_(avg)=(31713-31500)/(6.5)`

`v_(avg)=(213)/(6.5)`

`v_(avg)=32.77\ mi/hr`

Thus the average velocity of mail truck is
`32.77\ mi/hr`
