The latitude and longitude for 46 degrees North latitude from the Prime Meridian are approximately 46 degrees North latitude, 0 degrees longitude. Moving to 21 degrees South, 35 degrees West would take you to approximately 21 degrees South latitude, 35 degrees West longitude. Continuing to 20 degrees South, 45 degrees West would position you at approximately 20 degrees South latitude, 45 degrees West longitude. Finally, moving to 20 degrees North would bring you around 20 degrees North latitude, along the same longitude as the previous location (45 degrees West).
The coordinates 30 degrees north, 45 degrees west are located in the North Atlantic Ocean. This point is approximately halfway between the coasts of North America and Africa. The North Atlantic Ocean is the second largest of the world's oceans, covering an area of about 41,100,000 square miles.
A magnetic declination of 45 degrees can be either east or west, depending on the location. If it is 45 degrees east, it means that magnetic north is 45 degrees to the east of true north. If it is 45 degrees west, it means that magnetic north is 45 degrees to the west of true north.
