Question

What is the time difference between two consecutive lines of longitude?

विकल्प

• 7½ minutes

• 4 minutes

• 1 minute

• 3 minutes

Answer 1

4 minutes

Explanation:

The Earth rotates 360° in 24 hours, which means it rotates 15° every hour. Therefore, for each degree of longitude, the time difference is 4 minutes (since 60 minutes ÷ 15° = 4 minutes). So, the time difference between two consecutive lines of longitude is 4 minutes.
