A ship is sailing due north. At a certain point, the bearing of a lighthouse 3.3 km away is N38.3°E. Later on, the captain notices that the bearing of the lighthouse has become $32.3°E. How far did the ship travel between the two observations of the lighthouse? The ship travelled km between the two observations. (Do not round until the final answer. Then round to the nearest tenth as needed.)
