\r\n" );
document.write( "Let x be the speed of the scooter, in km/h.\r\n" );
document.write( "\r\n" );
document.write( "Then the speed of the plane is 5x km/h.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The time for the scooter to travel 600 km is    hours.\r\n" );

document.write( "\r\n" );
document.write( "The difference of these amounts of time is 6 hours.\r\n" );
document.write( "\r\n" );
document.write( "So we write this \"time\" equation\r\n" );

document.write( "ANSWER.  The speed of the scooter is  80 km/h.  The speed of the plane is 5*80 = 40 km/h.\r\n" );
