Question 31Navigation Problems

The correct answer is B) 1131. To determine the zone time of the Local Apparent Noon (LAN), we need to calculate the time it takes for the vessel to reach the longitude where the sun is directly overhead (local meridian). Given: - Initial position: LAT 28°35'S, LONG 82°30'W - Course: 300°T - Speed: 20.0 knots The vessel is heading towards the west, and the time it takes to reach the local meridian (LONG 0°) can be calculated using the distance and speed. The distance traveled from the initial position to the local meridian (82°30'W) is 82.5 degrees. At a speed of 20.0 knots, it takes the vessel 4 hours and 7 minutes to reach the local meridian. Therefore, the zone time of LAN is 1131. The other options are incorrect because: A) 1225 is too late, as the vessel would have already passed the local meridian. C) 1211 is too early, as the vessel would not have reached the local meridian yet. D) 1158 is also too early, for the same reason as option C.
