Because the Headquarters of the Admiralty, the British Royal Navy, were in Greenwich, SE London, when the measurement of Longitude was discovered.
The time meridian is each standard time zone roughly centered on a line of longitude exactly divisible by 15 degrees and the prime meridian is the starting point for the standard time zones an arbitrary longitude line.
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.
This is called the Prime meridian, it passes through Greenwich, England.
The Midnight Meridian refers to the line of longitude directly opposite the Prime Meridian, marking the halfway point between the International Date Line and the Prime Meridian. It is where each calendar day begins.
-- The longitude of the Prime Meridian is zero. -- Every point on the Prime Meridian has a different latitude. -- For every possible latitude, there is a point on the Prime Meridian.

yes

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 1/2 of the boundary between the eastern and western hemispheres.
The Prime Meridian, ie 0 degrees longitude, runs through the London suburb of Greenwich.

No, the prime meridian (0 degrees longitude) defines the dividing line between the Eastern and Western Hemispheres. The 180th meridian (opposite of the prime meridian) is the International Date Line, which primarily serves as the line where one day ends and another begins.
The International Date Line and the Prime Meridian both separate the eastern from the western hemisphere.
