Question 93Navigation Problems

The correct answer is D) 1213. To determine the time of local apparent noon (LAN), we need to calculate the longitude of the vessel and use it to find the time difference between the vessel's time zone and the local time at the vessel's position. Given: - The vessel's position at 0800 zone time is LAT 25°25.0'S, LONG 16°09.0'W. - The vessel is on course 290°T at a speed of 13.5 knots. The longitude of the vessel is 16°09.0'W, which corresponds to a time difference of 1 hour 4 minutes and 36 seconds (16°09.0'W / 15° per hour = 1.0775 hours = 1 hour 4 minutes and 36 seconds) earlier than the zone time. Since the zone time is 0800, the local apparent noon (LAN) will be 1213. The other options are incorrect because: A) 1157 is too early B) 1205 is too early C) 1209 is too early
