\r\n" );
document.write( "\r\n" );
document.write( "Let \"d\" be one way distance (the unknown value under the problem's question).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then you have this \"time\" equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     +  = 6 hours.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Notice that the addends in the left sides are the times traveling in each direction.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve the equation, multiply both sides by 12.  You will get\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    3d + 2d = 6*12\r\n" );
document.write( "\r\n" );
document.write( "      5d    = 72\r\n" );
document.write( "\r\n" );
document.write( "       d    = 72/5 = 14.4 miles.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   +  = 3.6 + 2.4 = 6 hours.   ! Correct !\r\n" );
