With only a large valve open, all of the liquid can be drained from the same vat in 2 hours.
How long would it take to drain the vat with both valves open?
:
Let t = time required when both valves are open
Let the completed job = 1; (an empty vat)
:
The equation + = 1
:
multiply by 4, to clear the denominators and solve for t, change the decimal portion to minutes
