I don't think you mean the Prime Meridian. I think you mean the Equator, latitude not longitude. King Neptune is, I suspect, what you refer to. The Prime meridian is 0 degrees longitude, the Greenwich Meridian. the Equator is 0 degrees latitude & circles the Earth horizontally.
If you are crossing the Prime Meridian and the altitude of Polaris is 50 degrees, you are located at a latitude of approximately 50 degrees north. The Prime Meridian is at 0 degrees longitude, so your exact location would be 50°N, 0°E. This position places you in the North Sea, near the eastern coast of England.
This is called the Prime meridian, it passes through Greenwich, England.
It is sometimes called the Greenwich meridian or 0° longitude.
Assuming that "all the way west of the Prime Meridian" would be on the opposite side of the globe from the prime meridian, or at 180o, "halfway west of the Prime Meridian" would be the 90oW meridian.
The Prime Meridian is defined as Zero Longitude. Any longitude that you feel is "close" to zero is close to the Prime Meridian.

That would be the Prime Meridian.

No. That would be the International Date Line.The Prime Meridian is defined as zero longitude.

Eastern side of USA is nearer the Greenwich meridian in London UK.
It would depend on the date, as the position of the sun crossing the meridian changes each day due to Earth's tilt. Generally, at 10 am EST, the sun's longitude when crossing the meridian would be around 30 degrees west.
You would be closer to the Prime Meridian on the eastern coast of South America. The Prime Meridian is located at 0 degrees longitude and runs through Greenwich, near London, England. Therefore, the further east you go from the Prime Meridian, the higher the longitude values will be.
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.
