Question 1736Navigation General70% to pass
A ship is in longitude 54°00'W on a true course of 090°. The ship's clocks are on the proper time zone. At what longitude should the clocks be changed to maintain the proper zone time?
AI Explanation
The correct answer is A) 52°30'W.
The reason this is the correct answer is that when a ship is sailing on a true course of 090° (east), it is crossing time zones that are 15 degrees apart. Since the ship's current position is at 54°00'W, it should change its clocks when it reaches 52°30'W, which is the next time zone boundary 15 degrees to the east.
The other options are incorrect because B) 67°30'W is too far east, C) 45°00'W is too far west, and D) 60°00'W is also too far east of the ship's current position.
