Answer:
The Prime Meridian is a line that divides the earth and is defined as being Zero degrees Longitude. This line also separates the Eastern and Western Hemispheres.
The Prime Meridian Passes through Greenwich Village which is where (true) noon is. The Prime Meridian is Zero Degrees Longitude and the International Date Line is 180 Degrees Longitude. Latitude and Longitude is used for Navigation. Longitude is used to divide time zones.
Long ago (mid 1800's) the American railroads and the Royal Navy needed to divide the world into "zones of time" to prevent accidents on the railroads and to predict sailing/shipping times.
A convention met with several dozen countries contributing, but since the best mapping of the world had been done by British sailors at sea and soldiers on land, the starting point for these time zones and the starting point for future mapping was decided by the British Navy, and they chose the point of their own Naval Observatory in Greenich, England, a suburb of London.
Thus, the zero degree point is in Greenwich, and Greenwich time is called "Zulu" (Phoenitic alaphabet for the letter "z" for zero) All latitude west of there is so many degrees West, and all points to the east are in degrees latitude East.
