On 2 January you are on a course of 094°T at a speed of 20 knots. At 0430 ZT, your DR position is LAT 24°12'N, LONG 71°24'W. Determine the zone time of sunrise.

Correct Answer: Option D — 0627

Using the Nautical Almanac, find the LMT of sunrise for the DR latitude. Convert LMT to ZT by applying the longitude correction (15° per hour). For 71°24'W, the correction is 4 hours 45 minutes 36 seconds. Applying this to the LMT yields 0627 ZT.
