Question

Explain why 1 degree latitude is equal to 111km only at the equator

Answer 1

Answer:

Since the Equator is a large circle and the perimeter of a circle is equals to 3600, 10 angular length is roughly equal to 111 km. ... However, this is not the case with the lines of the latitude, since these lines are notably apart at the equator, where 1 degree of the latitude is equal to 111 km.
