The easiest way to set up these types of problems:
\r
\n" ); document.write( "\n" ); document.write( " $\"1%2Fpipe%2B1%2Fhose=1%2Fx\"$
\r
\n" ); document.write( "\n" ); document.write( " $\"1%2F12%2B1%2F30=1%2Fx\"$
\r
\n" ); document.write( "\n" ); document.write( " $\"30%2F360%2B12%2F360=1%2Fx\"$
\r
\n" ); document.write( "\n" ); document.write( " $\"42%2F360=1%2Fx\"$
\r
\n" ); document.write( "\n" ); document.write( " $\"42x=360\"$
\r
\n" ); document.write( "\n" ); document.write( " $\"x=360%2F42\"$
\r
\n" ); document.write( "\n" ); document.write( " $\"x=60%2F7\"$
\r
\n" ); document.write( "\n" ); document.write( "It will take approximately 60/7 hours to fill the pool using both the hose and the pipe.
\r
\n" ); document.write( "\n" ); document.write( "This is about 8.57 hours, which makes numerical sense, since it will obviously be faster to fill the pool using both methods rather than one method alone.
