* The Prime Meridian is a line of longitude that divides the Earth into the Eastern and Western Hemispheres.

* Everything east of the Prime Meridian is in the Eastern Hemisphere, and everything west is in the Western Hemisphere.

So, to answer your question, any two places that are both in the Eastern Hemisphere or both in the Western Hemisphere would fit the description.

For example:

* London, England (East) and Paris, France (East) are both east of the Prime Meridian.

* Los Angeles, California (West) and San Francisco, California (West) are both west of the Prime Meridian.
