Question 459935: one hose can fill a goldfish pond in 42 minutes, and two hoses can fill the same pond in 30 minutes. find how long it takes the second hose alone to fill the pond Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 1/42+1/t=1/30
1/30-1/42=1/t
7/210+5/210=1/t=12/210
t=210/12=35/2
It takes the second hose 35/2 minutes to fill the pool alone.
