155. On 20 November your 1030 ZT DR position is LAT 27°16.0'N, LONG 157°18.6'E. You are on course 060°T at a speed of 20 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 1200 running fix.

The 1200 running fix is determined by the intersection of celestial lines of position advanced from their original times, considering the vessel's course and speed. Based on these calculations and a comparison to the expected DR track, the correct latitude and longitude are 2729.7'N and 15743.0'E.
