Question

The distance of the equator from either of the poles is

Answer 1

Easy, there are 90 degrees of distance from the equator to the North Pole. Each degree has 60 minutes, each minute = 1 nautical mile, therefore 60 x 90 = 5,400 nautical miles. Angle between the equator and North Pole is 90°. 1 nautical mile = 1852 meters = 1'; 1° = 60'; just multiply 60 x 90 x 1852.

Answer 2

The original definition of a kilometer was 1/10,000 of the distance from the equator to the North Pole, but measurements have improved. Easy, there are 90 degrees of distance from the equator to the North Pole. Each degree has 60 minutes, each minute = 1 nautical mile, therefore 60 x 90 = 5,400 nautical miles.
