Question

It takes 45 min for Faucet A to fill a tank, and it takes Faucet B 63 min. How many minutes will it take the two faucets to fill the tank together?

Answer 1

the total minutes taken together is 26.25 minutes

Explanation:

The computation of the number of minutes that required to fill the tank together is shown below:

`(1)/(45) + (1)/(63) = (1)/(x)\\\\(7 + 5 )/(315) = (1)/(x) \\\\(12)/(315) = (1)/(x) \\\\12x = 315\\x = 26.25`minutes

Hence, the total minutes taken together is 26.25 minutes
