A tank can be filled in 2 hours. The same tank can be emptied in 6 hours. If the faucet is on and the drain is left open, when will the tank overflow
\n" ); document.write( ".
\n" ); document.write( "Let x = time (hours) when tank overflows
\n" ); document.write( "then
\n" ); document.write( "x(1/2 - 1/6) = 1
\n" ); document.write( "multiplying both sides by 6:
\n" ); document.write( "x(3 - 1) = 6
\n" ); document.write( "x(2) = 6
\n" ); document.write( "x = 6/2
\n" ); document.write( "x = 3 hours
\n" ); document.write( "
\n" );
