You can put this solution on YOUR website!
Assuming 650 km/hr is the air speed:
\n" ); document.write( "\"Ground+speed+=+sqrt%28650%5E2+%2B+35%5E2%29\"
\n" ); document.write( "=~ 650.94 km/hr
\n" ); document.write( "or ~ 651 km/hr
\n" ); document.write( "---------------
\n" ); document.write( "Its ground track is 270º + arctan(35/650)
\n" ); document.write( "=~ 273.1º
\n" ); document.write( "You asked for velocity. Velocity is a vector with components of speed and direction.
\n" ); document.write( "---------------
\n" ); document.write( "PS Aviation and weather people us knots for speed, not km/hr or miles/hr.
