Question 898080: One water pipe fills a water tank in x hours. A second pipe takes 3 hours longer. The two pipes
together fill the water tank in 2 hours. How long would it take each pipe to fill the water tank
separately?
You can put this solution on YOUR website! Add their rates of filling to get their
rate filling together
1st pipe's rate:
( 1 tank ) / ( x hrs )
2nd pipe's rate:
( 1 tank ) / ( x + 3 hrs )
Rate with both pipes filling:
( 1 tank ) / ( 2 hrs )
----------------------------
Multiply both sides by ( by inspection ) is the positive answer, so
-----------------
The 1st pipe takes 3 hrs
The 2nd pipe takes 6 hrs
