On 24 January your 0700 zone time DR position is LAT 22°25.0'N, LONG 46°10.0'W. Your vessel is on course 110°T at a speed of 12.0 knots. What is the zone time of local apparent noon (LAN)?

Correct Answer: Option C — 1212

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 movement toward the sun.
