Q: If it is 12:00 noon at the Prime Meridian (0° longitude), what time is it at 45°E longitude?

Solution: Each degree of longitude represents 4 minutes of time. Therefore, at 45°E, it is 45 * 4 = 180 minutes or 3 hours ahead, making it 3:00 PM.

Steps: 7

Step 1: Understand that the Prime Meridian (0° longitude) is the starting point for measuring time around the world.
Step 2: Know that each degree of longitude represents a time difference of 4 minutes.
Step 3: Calculate the time difference for 45°E longitude by multiplying 45 degrees by 4 minutes per degree.
Step 4: Perform the calculation: 45 * 4 = 180 minutes.
Step 5: Convert 180 minutes into hours: 180 minutes is equal to 3 hours.
Step 6: Since 45°E is east of the Prime Meridian, add the 3 hours to the time at the Prime Meridian (12:00 noon).
Step 7: Calculate the final time: 12:00 PM + 3 hours = 3:00 PM.

If it is 12:00 noon at the Prime Meridian (0° longitude), what time is it at 45°E longitude?
