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 C — 1156

Calculate the longitude difference between the DR position and the zone meridian. Convert this difference into time at a rate of 4 minutes per degree. Apply this correction to 1200 to find the local apparent noon, accounting for the vessel's eastward movement toward the sun.
