What does the distance covered by a degree of longitude depend on?

It depends on the latitude where you measure it.
It's about 69 miles on the equator, and it shrinks to zero at the poles.
In general, at any latitude,
Distance covered by 1 degree of longitude =
*** (69 miles) x [ cosine(latitude where it's measured) ]***

The distance covered by a degree of longitude varies with latitude: it is about 69 miles at the equator and decreases to zero at the poles. This decrease can be calculated using the formula: Distance = 69 miles × cos(latitude). Therefore, the higher the latitude, the shorter the distance covered by a degree of longitude.
