document.write( "Let x be Mark' speed in \"km%2Fh\". Then tom' speed is x-5 \"km%2Fh\"\r\n" );

document.write( "Since they move toward each other, the rate of decreasing the distance between them is x + (x-5) = 2x-5 \"km%2Fh\".\r\n" );

document.write( "The time they spent for their trip is 1 hour 12 minutes, or \"6%2F5\" of an hour.\r\n" );
