You can put this solution on YOUR website!
The inlet pipe can fill 1/6 of the pool per hour, the drain empties 1/8 of the pool per hour.
\n" ); document.write( "In x hours, (x/6)-(x/8)=1/2
\n" ); document.write( "multiply through by 24
\n" ); document.write( "4x-3x=12
\n" ); document.write( "x=12 hours ANSWER
\n" ); document.write( "The inlet pipe will fill the equivalent of 2 pools, and the drain empties the equivalent of 1.5 pools, for half a pool. \n" ); document.write( "

\n" );
