document.write( "If yellow light is x seconds, then the green light lasts 8x seconds and the red light lasts 11x seconds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    x + 8x + 11x = 80\r\n" );

document.write( "Answer.  Yellow light lasts 4 seconds; green  4*8 = 32 seconds  and  red light 11*4 = 44 seconds.\r\n" );
