Question 754882: A tap fill a tank in 60 minutes & other can empty it in 50 minutes.if the tank is full & both the taps are opened in wat time will the tank be emptied? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Add the rate of filling and subtract the
rate of emptying
The rate of filling is:
( 1 tank filled ) / ( 60 min )
The rate of emptying is:
( 1 tank empty ) / ( 50 min )
Let = time to empty tank
---------------------------
( note that the right side is negative because it
is an emptying rate )
Multiply both sides by
The tank is emptied in 300 min
or, 5 hrs
---------
check:
OK
