Depends on the winds aloft and the direction of the plane relative to the wind direction.
\n" ); document.write( "Typically airplane speeds are given relative to the ground with zero wind.
\n" ); document.write( "So of the wind speed is zero, then V=240 mph.
\n" ); document.write( "If the plane travels into a 100mph head wind, then V=240-100=140 mph.
\n" ); document.write( "If the plane travels into a 100mph tail wind, then V=240+100=340 mph.
\n" ); document.write( "
\n" );
