Look up the cities here, and note their LATITUDE. The one with the smallest latitude is the closest to the equator.

If the time is 1:00p.m. Greenwich Time, What time would it be at the 170 E Longitude lines?

To determine the time at a specific longitude, you need to know the time difference between that longitude and the reference point of Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC).

Longitude lines are divided into 15-degree intervals, with each interval representing one hour. Moving east from the GMT line, the time increases by one hour for every 15 degrees of longitude, and moving west, the time decreases.

In this case, the 170° E longitude is in the eastern hemisphere. Since this longitude is 170 degrees east of the Greenwich Meridian (0°), you need to calculate the time difference.

To calculate the time difference in hours, divide the longitude by 15:
170°E / 15° = 11.33 hours

The result of 11.33 hours indicates that the 170° E longitude is 11 hours and 20 minutes ahead of Greenwich Mean Time (or UTC).

Therefore, if it is 1:00 p.m. GMT, the time at the 170° E longitude would be approximately 12:20 a.m. the following day.
