Every point on earth in the Western Hemisphere fits that description.
The distance east or west from the Prime Meridian is measured in degrees, with 360 degrees in a full circle representing the Earth's circumference. The Prime Meridian itself is set at 0 degrees longitude, so any location east of it will have a positive longitude value, while any location west of it will have a negative longitude value.
The line of longitude for a place that is halfway between the prime meridian and the 80th line of longitude and west of the prime meridian would be -40 degrees longitude. The prime meridian is at 0 degrees, and halfway between 0 and 80 is 40 degrees. Since the location is west of the prime meridian, the longitude would be measured as negative.

The Prime Meridian is east of France. The Prime Meridian is located in Greenwich, England. This is the location on earth where the longitude coordinate is 0 degrees.
Degrees of longitude tell us how far east of west of the Prime Meridian a location is.
The distance from the prime meridian is usually measured in degrees of longitude. The distance east or west of the prime meridian is referred to as "longitude."
The Prime Meridian is the line of zero longitude that passes through the Royal Observatory, Greenwich, UK. Lines of longitude radiates outwards from the prime meridian towards the west and east. Latitude and longitude enable a location to be fixed on the Earth.
Location of a point on the surface of the earth.
The prime meridian is located at 0 degrees longitude.
You can determine if your location is east or west longitude by looking at the numerical value of your longitude coordinates. If the value is positive (+) then you are in the eastern hemisphere, indicating east longitude. If the value is negative (-) then you are in the western hemisphere, indicating west longitude.
