\n" ); document.write( "How long will the other tap take to fill the same tank?
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "The combined rate of work of the two taps is  1/12  of the tank volume per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The individual rate of work of one tap is 1/12.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the individual rate of work of the other tap is the difference\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    \"1%2F8\" - \"1%2F12\" = use the common denominator 24 = \"3%2F24\" - \"2%2F24\" = \"1%2F24\"  of the tank volume per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that the other tap will take 24 hours to fill the tank working alone.\r\n" );

\n" ); document.write( "\n" ); document.write( "This analysis using the rate of work is a simple and powerful method solving problems on joint work.\r
