9,000 to 10,000 knots. Assuming the observer's time estimate to be accurate, the object was obviously moving even faster. As the observer's line of sight (the angle bisector) moves from the normal (vertical at his position) the further removed from 90 degrees to this bisector becomes the object's path, and an equal angle now subtends even greater distance along this path.
