Greenwich. That's where the term GMT (Greenwich Mean Time) comes from.
London is the major city located at 51 degrees north latitude and 0 degrees west longitude in the UK. It is the capital and largest city in the United Kingdom.
The prime meridian, longitude 0° (zero degrees), runs through Greenwich in East London.
No. 90 degrees longitude is not a major line of longitude. Only 0 and 180 degrees longitude, which are the Greenwich Meridian and the International Date Line respectively, are major lines of longitude.
Difficult to explain without pictures, but here goes.... Imagine a circle drawn around the earth, from North to South and passing through both the North and South poles. This called a meridian, or Great Circle. A series of these circles can be drawn, each one being one degree apart, around the circle of the equator, and there would then be 360 such circles. The longitude of any place on earth is measured by how many degrees around is the meridian which passes through it. The starting point for this measurement could be anywhere on earth, but because of Britain's history as a major empire and sea power the starting point is in Greenwich, London. So, the longitude of Greenwich, London is 0 degrees.
The Prime Meridian runs through London, marking the 0° line of longitude. It is recognized as the starting point for measuring longitude and is located at the Royal Observatory in Greenwich, London.
Norway, Sweden, and the Czech Republic all lie at 15 degrees east longitude. Major rivers in these countries would also lie in this longitude.
The major line of longitude located at 180 degrees longitude is the International Date Line.
What city is located at 60 degrees latitude and 5 degrees longitude?

30 degrees north and 90 degrees west
The Prime Meridian passes through Greenwich, a major city in London, Great Britain. This imaginary line marks 0 degrees longitude and is a significant point for navigation and timekeeping.
