Water from a tank is being used for irrigation while the tank is being filled. The two inlet pipes can fill the tank in 6 h and 12 h,
respectively. The outlet pipe can empty the tank in 24 h. How long would it take to fill the tank with all three pipes open?
(Round your answer to one decimal place.)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
First pipe fills of the tank volume per hour.
The second pipe fills of the tank volume per hour.
The third pipe empties of the tank volume per hour.
When all three pipes turned on, they fill
= =
of the tank volume per hour.
Hence, it will take = hour = 4 hour 48 minutes to fill the tank if all three pipes are open and turned on.
