It takes 12 hours for a single hose to fill a large vat. when a second hose is added, the vat can be filled in 4 hours. how many hours are required for the second hose working alone to fill the vat? enter your answer in the box.

Its 6 hours.

I should probably explain it, the reason for this is mainly just by dividing the fact that adding the other hose takes away 8 hours of work we can deduce that the amount of water it can put out can do it 2 times faster than the normal hose so the answer is 6
