difference of longitude的用法详解
Difference of longitude, also known as the east-west distance, is the geographical distance between two points along the Earth’s equator. Longitude is measured east and west from the Prime Meridian (0 degrees longitude) to 180 degrees longitude (the International Date Line). The eastern hemisphere is measured east of the Prime Meridian and the western hemisphere is measured west of it.
Difference of longitude is calculated by subtracting the longitude of one point (in degrees) from the longitude of another point. For example, if the longitude of one location is 25 degrees east and the longitude of another is 39 degrees east, the difference of longitude between the two locations would be 14 degrees east.
Difference of longitude is sometimes used to calculate the travel time and distance between two points. The further east or west a location is from another, the faster time passes at that location. For example, if one person is located 3 degrees east of another person, the person east will experience time 1 minute and 16 seconds ahead of the person located west.
Difference of longitude is also important for navigation. Knowing the difference of longitude between two places can help sailors and pilots determine the direction in which they should travel. By calculating the difference of longitude, they can figure out the distance they need to travel and the bearing they will need to follow to reach their destination.
In summary, difference of longitude is used to measure the geographical distance between two points along the Earth’s equator. It is used to calculate the travel time and distance between two points and is also important for navigation.
