If it is noon at the Prime Meridian (0° longitude), what time is it at 90° East

If it is noon at the Prime Meridian (0° longitude), what time is it at 90° East longitude? (2020)

If it is noon at the Prime Meridian (0° longitude), what time is it at 90° East longitude? (2020)

Step 1: Understand that the Earth is divided into 360 degrees of longitude.
Step 2: Know that the Prime Meridian (0° longitude) is the starting point for measuring time.
Step 3: Realize that each 15 degrees of longitude represents a 1-hour difference in time.
Step 4: Calculate how many 15-degree sections are in 90 degrees by dividing 90 by 15.
Step 5: Perform the calculation: 90 ÷ 15 = 6. This means 90° East is 6 hours ahead of the Prime Meridian.
Step 6: If it is noon (12:00 PM) at the Prime Meridian, add 6 hours to find the time at 90° East.
Step 7: Add 6 hours to 12:00 PM, which gives you 6:00 PM.
