Robert spots an airplane on radar that is currently approaching in a straight line, and that will fly directly overhead . The plane maintains a constant altitude of 7475 feet. Robert initially measures an angle of elevation of 20 degrees to the plane at point A. At some later time, he measures an angle of elevation of 43 degrees to the plane at point B. Find the distance the plane traveled from point A to point B. Round your answer to the nearest tenth of a foot if necessary.
