It takes you 8 hours to dig a hole.
\n" ); document.write( "

\r\n" );
document.write( "Your rate is 1 hole per 8 hours or \r\n" );
document.write( "\r\n" );
document.write( " = \r\n" );
document.write( "

\n" ); document.write( "if your brother were to dig the hole by himself, how long would it take him?
\n" ); document.write( "

\r\n" );
document.write( "Let the answer be x hours.\r\n" );
document.write( "Your brother's rate is 1 hole per x hours or \r\n" );
document.write( "\r\n" );
document.write( " = \r\n" );
document.write( "

\n" ); document.write( "it takes you and your brother 5 hours to dig that same hole together.
\n" ); document.write( "

\r\n" );
document.write( "\r\n" );
document.write( "Then your combined rate is 1 hole per 5 hours or \r\n" );
document.write( "\r\n" );
document.write( " = \r\n" );
document.write( "\r\n" );
document.write( "The equation comes from:\r\n" );
document.write( "\r\n" );
document.write( "  \r\n" );
document.write( "\r\n" );

document.write( "\r\n" );
document.write( "     \r\n" );
document.write( "\r\n" );
document.write( "        \r\n" );
document.write( "\r\n" );
document.write( "Multiply through by LCD = 40x\r\n" );
