Question Find the time to fill a vat with two pipes, one filling in 3 hours, the other emptying in 8 hours, when both are left open.

Studdy Solution
Combine the hours and minutes to find the total time to fill the vat.
$$Time_{total} = 4\, hours + 48\, minutes$$
It will take 4 hours and 48 minutes to fill the vat if both pipes are left open.
