Explanations:Longitude is a coordinate that specifies the east-west position of a point on the Earth's surface. It is measured in degrees, minutes, and seconds, and it ranges from 0° at the Prime Meridian (which passes through Greenwich, England) to 180° east or west. The westernmost longitude of a country is the longitude line that passes through the westernmost point of that country.
In the case of India, the westernmost longitude is 68°7'E, which passes through the state of Gujarat. This means that the westernmost point of India is located at this longitude, and it is situated in Gujarat. The longitude is measured in degrees east (E) because it is located east of the Prime Meridian.
It is important to note that the westernmost longitude is not the same as the westernmost point of a country. The westernmost point is the geographical location that is furthest west, while the westernmost longitude is the line of longitude that passes through that point. In this case, the westernmost point of India is located in Gujarat, and the westernmost longitude that passes through this point is 68°7'E.
Understanding the concept of longitude is crucial for geographical studies and navigation. It helps in determining the position of a place on the Earth's surface and is used in various applications such as mapping, time zones, and global positioning systems (GPS).
