Answer:
The rate of speed for Harper's family trip is 4.75 miles per hour

The distance to the friend’s house is 276.45 miles.
It takes the family 5.82 hours to complete the trip.
We know the rate of speed per hour is calculated by dividing distance by time
![\text {rate of speed}=\frac{\text {distance}}{\text {time}}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/k83mvyvf9rfgmu5m4uaz69jcd6zattoiu0.png)
Here distance = 276.45 miles and time = 5.82 hours
Therefore, rate =
= 4.75 miles/hour
