Answer: 64.8 mph
Step-by-step explanation:
Given
Arriving time is 6 hours
return time is 4 hours
The average speed of returning 81 mph

the average speed of the entire trip is
![\Rightarrow v_{avg}=\dfrac{2\times 324}{6+4}=\dfrac{648}{10}=64.8\ mph](https://tex.z-dn.net/?f=%5CRightarrow%20v_%7Bavg%7D%3D%5Cdfrac%7B2%5Ctimes%20324%7D%7B6%2B4%7D%3D%5Cdfrac%7B648%7D%7B10%7D%3D64.8%5C%20mph)
