Question 1100984
Left on together, the cold and hot water faucets of a certain bathtub take 4 minutes to fill the tub. If it takes the cold water faucet 12 minutes to fill the tub by itself, how long will it take the hot water faucet to fill the tub on its own?
1/h+1/12=1/4
1/h+1/12=3/12
1/h=2/12
1h=1/6
h=6 minutes for hot water to fill the tub on its own.
check
1/6+1/12=1/4
2/12+1/12=3/12=1/4
ok
