Question

find out the distance between 40°north to 90°north​

Answer 1

Answer:

It can be stated in relative terms (about 3,000 miles west of New York, for example), but for a cartographer, pilot, geologist, or geographer, a much more specific measurement is needed. In order to precisely locate any spot in the world, therefore, we use a geographic coordinate system that is measured in degrees of latitude and longitude. This system starts with an imaginary grid of lines that cover the entire planet. Locations are measured based on both X and Y coordinates within the grid.
