On 14 October your 0800 zone time (ZT) dead reckoning position is LAT 28°22.0'N, LONG 161°17.0'E. Your vessel is on course 116°T at a speed of 17.5 knots. What is the ZT of local apparent noon (LAN)?

Correct Answer: Option B — 1156
Determine the longitude difference from the zone meridian (165°E). Adjust for the Equation of Time and the vessel's change in longitude during the transit to LAN. By calculating the time difference based on the vessel's speed and course, the resulting local apparent noon occurs at 1156 ZT.
