A bathtub can be filled in 8 min.

\n" ); document.write( ":
\n" ); document.write( "let t = time in min for this to happen
\n" ); document.write( "let a full tub = 1
\n" ); document.write( "fill is +; drain is -
\n" ); document.write( " $\"t%2F8\"$ - $\"t%2F12\"$ = 1
\n" ); document.write( "multiply eq by least common multiple of 8 & 12. That's 24.
\n" ); document.write( "Cancel the denominators and you have
\n" ); document.write( "3t - 2t = 24
\n" ); document.write( "t = 24 min to fill the tub in these conditions
\n" ); document.write( " \n" ); document.write( "

\n" );
