Question 376189: Faucet A fills a tank in 6 minutes, and faucet B fills the same tank in 12 minutes. If they are opened together to fill the same tank, how long will it take to fill the tank? Answer by amoresroy(361) (Show Source):
You can put this solution on YOUR website! Faucet A fills a tank in 6 minutes, and faucet B fills the same tank in 12 minutes. If they are opened together to fill the same tank, how long will it take to fill the tank?
Let x = the number of minutes it takes to fill the tank if Faucets A and B are
opened together
x(1/6 + 1/12) = 1
x(2/12 + 1/12)= 1
3x/12= 1
x = 4
It takes 4 minutes to fill the tank if Faucets A and B are opened together.
