On 28 May your 0200 DR position is LAT 19°16.5' S , LONG 119°24.0' W. You are on course 107°T at a speed of 18 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0600 running fix.

Correct Answer: Option D — LAT 19°43.0'S, LONG 117°54.0'W

Determining a running fix from an earlier Southern Hemisphere DR involves projecting the vector for 4 hours at 18 knots along course 107°T, successfully translating the celestial lines of position to LAT 19°43.0'S, LONG 117°54.0'W.
