On 7 February your 0800 zone time DR position is LAT 22°16.0'N, LONG 92°26.0'W. Your vessel is on course 270°T at a speed of 20.0 knots. What is the zone time of local apparent noon (LAN)?

Correct Answer: Option C — 1230

The DR position is 92°26.0'W, which is 2°26.0' east of the 90°W zone meridian. Converting this to time and accounting for the vessel's speed of 20 knots on course 270°T, the vessel reaches the meridian at 1230. This follows standard celestial navigation time-keeping procedures for determining LAN.
