Jai 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 5375 feet. Jai initially measures an angle of elevation of 15 to the plane at point A. At some later time, he measures an angle of elevation of 30 to the plane at point B. Find the distance the plane traveled from point A to point B. Round your answer to the nearest foot if necessary.
