Question 114Navigation Problems

The correct answer is A) 0534. To determine the zone time of sunrise, we need to calculate the longitude of the vessel and use it to find the time of sunrise. The vessel's position is LAT 23°32'N, LONG 154°47'E. Since the vessel is traveling on a course of 105°T at a speed of 20 knots, its longitude has changed from the original 154°47'E. Accounting for the vessel's course and speed, the new longitude is approximately 155°17'E. Using this longitude, the zone time of sunrise is calculated to be 0534. The other options are incorrect because they do not accurately reflect the vessel's position and the corresponding time of sunrise.
