Answer:
Not possible
Explanation:
It is not possible for a city to be located at 120° S and 30° W. It is because the earth is equally divided into into two hemispheres, where the latitudes starts from 0° at equator to 90° at poles, and the longitudes starts from 0° to 180° measuring from east to west direction or west to east direction.
Thus, no place can exist beyond 90° in both the hemisphere.
