\r\n" );
document.write( "Therefore Sam's typing rate is 5 pages per 10 minutes, or  which is ,\r\n" );
document.write( "or , \r\n" );
document.write( "

\n" ); document.write( ">>Tom can type 10 pages in 5 minutes,<<
\n" ); document.write( "

\r\n" );
document.write( "Therefore Tom's typing rate is 10 pages per 5 minutes, or  which is  ,\r\n" );
document.write( "or 2.\r\n" );
document.write( "

\r\n" );
document.write( "That says:\r\n" );
document.write( "Together, they can type x pages in 30 minutes.\r\n" );
document.write( "\r\n" );
document.write( "Therefore their combined typing rate is x pages per 30 minutes, or  or  ,\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( "                           + 2 = \r\n" );
document.write( "\r\n" );
document.write( "Multiply through by LCD = 30\r\n" );
document.write( "                           15 + 60 = x\r\n" );
document.write( "                                75 = x\r\n" );
document.write( "\r\n" );
document.write( "So together they can type 30 pages in 75 minutes or 1 hour 15 minutes.\r\n" );
