The trip there was with the wind.  It took 5 hours.  The trip back was into the wind.  The trip took 10 hours.  Find the speed of the plane in still air and the speed of the wind.  i know this should be relatively easy, but for some reason I am having a brain block and can't seem to make any headway on this problem.  Any help you can provide will be GREATLY appreciated! </SPAN>\n" );
