Question 488920: Pipe M can fill a tank in 36 hours, and pipe N can fill it in a certain time. If both pipes are opened simultaneously, the tank gets filled in 24 hours. Find the time it takes pipe N alone to fill the tank. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Pipe M can fill a tank in 36 hours, and pipe N can fill it in a certain time. If both pipes are opened simultaneously, the tank gets filled in 24 hours. Find the time it takes pipe N alone to fill the tank.
----
Pipe M rate: 1/36 job/hr
---
Pipe N rate: 1/x job/hr
---
Together rate: 1/24 job/hr
-----
Equation:
rate + rate = together rate
1/36 + 1/x = 1/24
24x + (24*36) = 36x
12x = (24*36)
x = 72 hrs (time for Pipe N to fill the tank alone)
