At 0450 zone time, on 25 June your DR position is LAT 21°26.0' N, LONG 160°24.5' W. You are steering course 100°T at a speed of 10 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0514 running fix.

Correct Answer: Option B — LAT 21°25.0'N, LONG 160°18.0'W

Updating celestial lines from 0450 to 0514 ZT requires applying a short-interval run vector based on course 100°T and 10 knots speed. Projecting the intercept lines across this 24-minute interval yields the precise running fix position of LAT 21°25.0'N, LONG 160°18.0'W.
