You can put this solution on YOUR website! One hose can fill a pond in 18 minutes, and two hoses can fill the same pond in 14 min. Find how long it takes for the second hose alone to fill the pond.
.
Let x = time (mins) it takes second hose alone
then
14(1/18 + 1/x) = 1
multiplying both sides by 18x:
14(x + 18) = 18x
14x + 252 = 18x
252 = 4x
63 minutes = x
