On 25 April your 1130 DR position is LAT 24°50.0'N, LONG 61°25.0'W. Your vessel is on a course of 300°T at a speed of 16.0 knots. Determine the zone time of (LAN) for your vessel.
AI Explanation
The correct answer is B) 1204.
To determine the zone time of the Local Apparent Noon (LAN), we need to calculate the vessel's longitude in degrees west and then use that to determine the time difference from Greenwich Mean Time (GMT).
Given information:
- Latitude: 24°50.0'N
- Longitude: 61°25.0'W
- Course: 300°T
- Speed: 16.0 knots
The longitude of 61°25.0'W is equal to 4 hours 5 minutes 40 seconds west of GMT. Since the vessel is traveling west, the time of LAN will be later than GMT.
Therefore, the zone time of LAN for the vessel is 1204, which is 4 hours 5 minutes 40 seconds later than GMT.
The other options are incorrect because they do not accurately reflect the vessel's position and the time difference from GMT.
