You can put this solution on YOUR website! The storage tank is 80 inches deep. After 3 hours of rain, the depth of water in the tank is 37 inches.
After 5 hours, the depth is 60 inches.
If the rain continues to fall at the same rate, how many hours will it take to fill the tank?
:
Find the inches per hour
37/3 ~ 12.3"
60/5 = 12"
About 12.15" per hr
80/12.15 = 6.6 hrs to fill the tank
