Time Difference Between 0° and 75°E Longitude Explained

Subject : Social Studies

Question:

“When the time is 12 noon at 0° longitude, the time at 75°E longitude will be?”

Expert Verified Solution:

When it is 12 noon at 0° longitude (also known as the Prime Meridian), the time at 75°E longitude can be calculated by considering the Earth’s rotation.

The Earth rotates 360° in 24 hours, which means it rotates 15° per hour. To find the time difference between two longitudes, you can divide the difference in degrees by 15.

Step-by-Step Calculation:

  • The difference between 0° and 75°E is 75°.
  • 75° ÷ 15° per hour = 5 hours.

Since 75°E is to the east of the Prime Meridian, it is ahead in time. Therefore, if it is 12 noon at 0° longitude, the time at 75°E will be:

12 noon + 5 hours = 5:00 PM.

Thus, the time at 75°E longitude will be 5:00 PM when it is 12 noon at the Prime Meridian.
