\r\n" );
document.write( "Let r be the speed of the slower-moving car, in miles per hour.\r\n" );
document.write( "\r\n" );
document.write( "Then the speed of the faster car is (r+10) mph.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The distance equation is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "4r + 4*(r+10) = 456.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "4r + 4r + 40 = 456\r\n" );
document.write( "\r\n" );
document.write( "8r = 456-40 = 416  ====>  r =  = 52.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  The speed of the slower-moving car is 52 mph.\r\n" );
