On 20 June your 0800 zone time DR position is LAT 21°02.0'N, LONG 152°50.0'E. Your vessel is on course 265°T at a speed of 15.0 knots. What is the zone time of local apparent noon (LAN)?

Correct Answer: Option B — 1154

Calculate the longitude difference from the zone meridian (150°E). Apply the Equation of Time for 20 June. Because the vessel is steaming west, the LAN time is delayed relative to the meridian. Solving the time-longitude relationship yields a local apparent noon time of 1154 ZT.
