On 9 February your 0830 zone time DR position is LAT 22°19.0'N, LONG 64°37.0'E. Your vessel is on course 128°T at a speed of 19.0 knots. What is the zone time of local apparent noon?

Correct Answer: Option A — 1152

Determine the time of LAN by calculating the difference between the vessel's longitude and the zone meridian. Adjust the DR position for the vessel's movement toward the meridian. The time correction, based on the longitude difference of 64°37'E, results in a local apparent noon time of 1152.
