document.write( "The question is about the average velocity.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Velocity is a vector; so we should determine the displacement from the starting to the ending point.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The displacement is 500 m - 200 m West,  or  300 m West.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The total time from the starting to the ending time moments is  29+35+65 = 129 seconds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now the average velocity =  =  = 2.33 m/s West.\r\n" );
document.write( "\r\n" );
