If it is 11 AM at the prime meridian, what time is it at 30 degrees west longitude?

Explanation:
Time zones follow longitude: every 15 degrees of longitude corresponds to a one-hour difference from Greenwich Mean Time (GMT/UTC). West of the prime meridian is behind GMT, east is ahead. So 30 degrees west is 2 hours behind GMT (30 ÷ 15 = 2). If it’s 11:00 AM at the prime meridian, at 30 degrees west it’s 2 hours earlier: 11:00 minus 2 hours = 9:00 AM. The other options would require different longitudes or moving east (ahead) instead of west.
