Question 1744Navigation General70% to pass
Your longitude is 124°E, and your local mean time is 0520 on the 5th of the month. The mean time and date at Greenwich is _______________.
AI Explanation
The correct answer is D) 2104 on the 4th.
To determine the correct answer, we need to calculate the time difference between your longitude (124°E) and the Greenwich Mean Time (GMT). Since your longitude is east of the prime meridian, you are ahead of GMT. The time difference is 124°E / 15° per hour = 8.27 hours, which rounds to 8 hours.
Therefore, your local mean time of 0520 on the 5th corresponds to a GMT time of 2104 (8.27 hours earlier) on the 4th.
The other options are incorrect because they do not properly account for the time difference between your location and GMT.
