First pipe: 1 tank/66min=1/66 tank/min*5/5=5/330 tank/min
\n" ); document.write( "Second pipe: 1 tank/55min=1/55 tank/min*6/6=6/330 tank/min
\n" ); document.write( "Together: 5/330 tank/min+6/330 tank/min=11/330 tank/min
\n" ); document.write( "To fill 1 tank: 1 tank/(11/330 tank/min)=330/11 min=33 minutes.
\n" ); document.write( "ANSWER: Using both pipes it takes 33 minutes to fill the tank.
