Detailed explanation-1: -Longitude is a measurement of location east or west of the prime meridian at Greenwich, London, England, the specially designated imaginary north-south line that passes through both geographic poles and Greenwich. Longitude is measured 180° both east and west of the prime meridian.

Detailed explanation-2: -The meridian 50° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Greenland, the Atlantic Ocean, South America, the Southern Ocean, and Antarctica to the South Pole.

Detailed explanation-3: -The Royal Observatory in Greenwich is where east meets west at Longitude 0°.

Detailed explanation-4: -Lines of longitude, also called meridians, are imaginary lines that divide the Earth. They run north to south from pole to pole, but they measure the distance east or west.

Detailed explanation-5: -LONGITUDE Lines of longitude run north-south, but provide east-west locational reference. Lines of longitude are called “meridians.” No two meridians are parallel to each other. Rather, all lines of longitude meet at both the North and South Poles, but are separated in between by varying distances.
