On 16 January your 0930 ZT DR position is LAT 26°07.0'S, LONG 51°43.0'E. Your vessel is on course 238°T at a speed of 17.0 knots. What is the ZT of local apparent noon (LAN)?
AI Explanation
The correct answer is B) 1145.
To calculate the time of local apparent noon (LAN), we need to use the given information about the vessel's position and course.
The key factors are the vessel's longitude (51°43.0'E) and the course (238°T). Using this information, we can calculate the time difference between the vessel's position and the local meridian, which is the point where the sun reaches its highest point in the sky. This time difference is then subtracted from 12:00 to determine the time of LAN.
The other options are incorrect because they do not correctly account for the vessel's longitude and course in relation to the local meridian.
