On 16 April your 0200 zone time DR position is LAT 17°18' S, LONG 168°46' E. You are on course 236°T at a speed of 16 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0600 running fix.

Correct Answer: Option B — LAT 18°00.4'S, LONG 167°49.2'E

Projecting a four-hour run from 0200 to 0600 at 16 knots on course 236°T advances the celestial lines of position. Applying this true course and distance interval to the initial DR results in LAT 18°00.4'S, LONG 167°49.2'E.
