The prime meridian passes through which city?

Explanation:
The main idea is recognizing that longitudes are measured from a starting line called the prime meridian, which is 0 degrees. This line runs from the North to the South Pole and passes through the Royal Observatory in Greenwich, a borough of London. Because the prime meridian is the reference for longitude, Greenwich is the city associated with this 0° line. The other cities sit at longitudes east or west of that line, so they aren’t on the prime meridian. This reference frame also ties to timekeeping, since time is standardized from Greenwich Mean Time, now UTC.
