Navigation Problems USCG Question #1145 (Set 34)

On 27 August your 0900 zone time DR position is LAT 24°25.0'N, LONG 94°20.0'W. Your vessel is on course 071°T at a speed of 20.0 knots. What is the zone time of local apparent noon (LAN)?

Official USCG Answer & Rule Citation

Correct Answer: Option A — 1214

Calculate the time of LAN by determining the longitude difference between the vessel's position and the standard meridian. Convert this difference into time (4 minutes per degree) and apply it to the 1200 zone time. The vessel's eastward movement further adjusts the time to 1214.
