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.
The distance between two latitudes is relatively constant at 111 kilometers because the lines of latitude are parallel to each other and evenly spaced. Whereas, the distance between two longitudes varies because the lines of longitude converge at the poles, resulting in shorter distances towards the poles and longer distances towards the equator.
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.
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).
The distance between longitudes decreases as you move towards the poles, so the exact distance between longitude 77 and 78 will vary depending on the latitude. However, as a general estimate, the distance between two longitudes decreases by approximately 69 miles for every degree you move towards the poles.

It is because all lines of longitude originate and converge there.
Their different longitudes differentiate between them.

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.
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.
