You have the following information:
- Davis family took 5 hours to travel to Silver Lake.
- The return took 7/8 of the time they took to travel to lake.
In order to determine how long did the return trip like take, you simply multiply the time to go to the lake by 7/8, just as follow:
(7/8)(5 h) = 4.375 h
Hence, the return trip took 4.375h
