On 13 February at 0325 zone time, your DR position is LAT 23°20'N, LONG 155°15'W. You are steering 240°T at a speed of 13.6 knots. What is the zone time of sunrise?

Correct Answer: Option D — 0657

Find the LMT of sunrise for the DR latitude in the Nautical Almanac. Convert to ZT using the longitude difference from the zone meridian (150°W). Adjust for the vessel's movement during the interval. The calculated zone time of sunrise is 0657.
