You can put this solution on YOUR website! Two hoses fill a pool in 2 hours. If only hose A is used, the pool is filled in 3 hours. How long would it take if only hose B is used?
.
Let x = time (hours) it takes for hose B alone
then
2(1/3 + 1/x) = 1
multiplying both sides by 3x:
2(x+ 3) = 3x
2x+ 6 = 3x
6 hours = x
.
answer: 6 hours
