At the equator, the circumference of the Earth is 40,075.16 km ( 24,901.55 miles). Divide that into 360 equal pieces to get the distance for each one degree of longitude. A degree of longitude at the equator is equal to 111.32 km.
All longitudes converge at the north and south poles, so the extent of 1 degree
depends on where you are.
1 degree of longitude covers 111 km at the equator, and zero distance at the poles.
In between, the distance represented by 1 degree of longitude is
111 km x (cosine of your latitude) .
69.17 miles per degree of longitude, at the equator
The equator marks zero latitude, and it has
a point on it at EVERY longitude.
All longitudes converge (meet, come together) at the north and south pole. A drawing ofthe globe with some of the meridians added looks like the drawing of a peeled orange, andthe distance between two meridians depends on how far from the equator you measure it.One degree of longitude measured along the equator represents a distance of about 69.1 miles (111 km),and it shrinks steadily to zero at the poles.In general, it's(distance measured at the equator) multiplied by (cosine of the latitude where you measure it)
That depends on your latitude. Longitudes all taper closer together, likethe ribs of a tangerine, as you move from the equator to the poles, andall longitudes meet in a single point at each pole.One degree of longitude represents a distance of about 111.1 km (69 miles)on the equator, and zero at either pole.At any latitude, the distance between two consecutive degrees of longitude is (69 miles) times (cosine of the latitude).
It is because all lines of longitude originate and converge there.
East and west distances can be measured using longitude lines, imaginary lines that connect the Earth's poles. The distance between any two longitudes is the greatest at the equator, and zero at the poles.
Their different longitudes differentiate between them.

The same as the total number of different lengths that can be measured on a3-foot ruler. If you name two longitudes, then no matter how close togetherthey are, I can always name another longitude that's in between yours. Sothere's no limit to the number of different longitudes that we can name.
The difference in local mean time between two longitudes is the difference in longitudes divided by 15 degrees per hour (15 degrees/hour). The difference in standard times between any two places depends on the government or governments that has/have jurisdiction over the places involved.
Ignoring curvature of the earth, and assuming a mean Earth radius of 3960 miles, then the distance between lines of longitude that are 1 degree apart = 3960 * 2 * pi /360 * cosine (of latitude) in miles. At the equator it is about 69 miles, at the poles it is zero.
