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?
AI Explanation
The correct answer is A) 1152.
To determine the zone time of local apparent noon, we need to calculate the vessel's longitude at local apparent noon, and then use that to find the corresponding zone time.
Given the vessel's position, course, and speed, we can calculate the longitude at local apparent noon by using the formula: Longitude at local apparent noon = Initial longitude + (19.0 knots * 4 minutes). This gives a longitude of 64°41.0'E, which corresponds to a zone time of 1152.
The other options are incorrect because they do not accurately calculate the longitude at local apparent noon and the corresponding zone time.
