130. On 15 July your vessel is enroute from Portland, OR, to Singapore, Malaysia. You are steering course 243°T and making a speed of 16 knots. Your 1845 zone time DR is LAT 27°42.0'N, LONG 167°02.0'E. You observed 3 celestial bodies. Determine the latitude and longitude of your 1945 running fix.

The correct running fix is determined by advancing the DR and plotting the intersection of three celestial lines of position (LOPs) at 1945, resulting in a position of 2731.1′ N, 16643.0′ E. This position aligns with the ship's course and distance run, and is consistent with the expected latitude decrease due to the southwesterly heading.
