When used alone, pipe A can fill the entire tank in 6 hours, and pipe B can fill the entire tank in 3 hours. If both pipes are used together, how long will it take to fill the entire tank?
Answer provided by our tutors
let
x = the number of hours the needed for the pipes to fill the entire tank together
1/x tank per hour is the rate of the pipes when working together
1/6 tank per hour is the rate of pipe A
!/3 tank per hour is the rate of pipe B
1/6 + 1/3 = 1/x
by solving we find:
x = 2 hr
