Detailed explanation-1: -Travel along the Equator following will mean the shortest distance between two places on the earth’s surface.
Detailed explanation-2: -The shortest distance between any two points on the surface of a sphere is called the Great Circle, a part of which is shown in the diagram as a dashed line. This circle is concentric with the center of the sphere.
Detailed explanation-3: -The Distance Formula. The shortest distance between two points is a straight line. This distance can be calculated by using the distance formula. The distance between two points ( x 1, y 1 ) and ( x 2, y 2 ) can be defined as d = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 .
Detailed explanation-4: -As proved below, the shortest path on the sphere is always a great circle, which is the intersection of the sphere with a plane through the origin.
