At 1400 zone time on 11 April, your DR position is LAT 25°40'N, LONG 91°00'W. You are steering 180°T at a speed of 10.0 knots. What is your zone time of sunset?

Correct Answer: Option D — 1825

Determine the sunset time by entering the Nautical Almanac with the vessel's latitude and date. Calculate the DR position at the approximate time of sunset. Apply the longitude correction to the tabular time to find the local zone time, which results in 1825 for the specified coordinates.
