You are in LONG 144°E. The date is 6 February, and the zone time is 0800. The Greenwich date and time are _______________.
AI Explanation
The correct answer is A) 2200, 5 February.
To determine the Greenwich date and time, we need to convert the local time at longitude 144°E to the Greenwich time. The time zone difference between 144°E and Greenwich is 9 hours, with 144°E being ahead of Greenwich. Therefore, subtracting 9 hours from the local time of 0800 on February 6 gives us the Greenwich time of 2300 on February 5.
The other options are incorrect because:
B) 2300, 5 February is too late, as the time zone difference should be 9 hours, not 10 hours.
C) 1700, 6 February is the local time at 144°E, not the Greenwich time.
D) 1800, 6 February is also the local time at 144°E, not the Greenwich time.
