You can put this solution on YOUR website! A winery has a vat with 2 pipes leading to it.
The inlet pipe can fill the vat in 7 hours while the outlet pipe can empty in 10 hours.

:
let t = time to fill the vat when both valves are open
let the completed job = 1 (a full vat)
:

3t = 70
t = 70/3
t = 23 hrs to fill the vat
