You are in LONG 165°E, zone time at 0400, 1 November. What is the zone time and date in LONG 165°W?

A 1800, 31 October
B 0600, 1 November
C 1800, 1 November
D 0600, 31 October
AI Explanation

The correct answer is D) 0600, 31 October. The explanation is as follows: 1) When you are in LONG 165°E, the time zone is 11 hours ahead of UTC. At 0400 on 1 November in that time zone, the UTC time is 1700 on 31 October. 2) Since the question asks for the time in LONG 165°W, which is 11 hours behind UTC, the zone time at 1700 UTC on 31 October is 0600 on 31 October. 3) The other options are incorrect because A) is 3 hours too early, B) is 1 hour too early, and C) is 12 hours too late. 4) The key is to properly account for the time zone difference between the two longitudes, which is a total of 22 hours (11 hours ahead and 11 hours behind).
