document.write( "Let \"x\" be the distance.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then your \"time\" equation is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     -  = 2    hours.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is really a \"time\" equation, since every ratio in the left side is the time of traveling !\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve the equation, multiply both sides by 48*60. You will get\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    60x - 48x = 2*48*60.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    12x = 2*48*60  ====>  x =  = 2*4*60 = 8*60 = 480.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The distance is 480 kilometers.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.    -  = 10 - 8 = 2 hours.    ! Precisely correct !\r\n" );
