121. On 19 November your 0200 zone time DR position is LAT 18°41'N, LONG 150°37'E. You are on course 014°T at a speed of 18 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0600 running fix.

The correct answer is determined by advancing the initial DR position based on speed and course, then plotting celestial lines of position and intersecting them at the specified time. This process yields a latitude of 1945.4'N and a longitude of 15052.6'E, which aligns with the expected track and reasonable set and drift.
