In 12 minutes running the warm tap only would produce 1 tub of water.
In 12 minutes running the cold tap only would produce 4/3 tub of water.
 12 minutes of running warm and cold would produce 7/3 tubs of water

So 1 tub of warm and cold would take 12/(7/3) = 5.14 minutes 
Approx 5 minutes and 8.6 seconds
