For example, 30Â°E, the line passing through eastern Africa, is an angular distance of 30Â° east of the Prime Meridian. 30Â°W, which is in the middle of the Atlantic Ocean, is an angular distance of 30Â° west of the Prime Meridian.
Because latitude runs from the equator to one or the other of the poles, 90 degrees. That's one-fourth of a full circle around the globe. Longitude starts at Greenwich, Englanâ¦d and runs, to the west or to the east, to the International Date Line (in the Pacific Ocean), 180 degrees.
