document.write( "\r\n" );
document.write( "The rate 60 mph is 1 mile per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In 5 minutes, the truck will have 5 miles head start comparing with the car.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Their relative speed is 70-60 = 10 mph.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that the distance between them decreases at the rate of 10 miles per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the car will catch the truck in   = 0.5 of an hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The car will overtake the car in 0.5 of an hour, or in 30 minutes.\r\n" );
