Makayla 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 5750 feet. Makayla initially measures an angle of elevation of 16^{\circ} ∘ to the plane at point AA. At some later time, she measures an angle of elevation of 31^{\circ} ∘ to the plane at point BB. Find the distance the plane traveled from point A to point B. Round your answer to the nearest foot if necessary.
