document.write( "Let  \"r\"  be the rate of the slower train, in km/h/\r\n" );
document.write( "\r\n" );
document.write( "Then the rate of the faster train is (r+20) km/h.\r\n" );

document.write( "\r\n" );
document.write( "6r + 6*(r+20) = 1692    kilometers\r\n" );

document.write( "\r\n" );
document.write( "6r + 6r + 120 = 1692\r\n" );
document.write( "\r\n" );
document.write( "12r = 1692 - 120 = 1572  ====>  r =  = 131.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  The slower train speed is 131 km/h.  The faster train speed is 131+20 = 151 km/h.\r\n" );
