\r\n" );
document.write( "This problem is very special.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In this problem, we have two halves of the entire way,\r\n" );
document.write( "and the halves are, of course, of equal length.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "For this specific situation, the simplest way to find the average speed is to use well known formula\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "   average speed =  =  =  = 3 = 3.111111111... miles per hour.   ANSWER\r\n" );

\n" ); document.write( "\n" ); document.write( "This formula is specially derived and works only for the case,
