If it is 12:00 noon at the Prime Meridian (0 degrees longitude), what time is it

If it is 12:00 noon at the Prime Meridian (0 degrees longitude), what time is it at 45 degrees East longitude? (2020)

If it is 12:00 noon at the Prime Meridian (0 degrees longitude), what time is it at 45 degrees East longitude? (2020)

Step 1: Understand that the Prime Meridian (0 degrees longitude) is the starting point for measuring time.
Step 2: Know that the Earth is divided into 360 degrees of longitude.
Step 3: Realize that the Earth rotates 15 degrees of longitude every hour.
Step 4: Calculate how many hours ahead 45 degrees East is by dividing 45 degrees by 15 degrees per hour: 45 / 15 = 3 hours.
Step 5: Add the 3 hours to the time at the Prime Meridian (12:00 PM): 12:00 PM + 3 hours = 3:00 PM.
Step 6: Conclude that at 45 degrees East longitude, it is 3:00 PM.

Time Zones – Understanding how time changes with longitude, specifically that the Earth is divided into 24 time zones, each representing 15 degrees of longitude.
Longitude Calculation – Calculating time differences based on degrees of longitude, where each 15 degrees corresponds to a one-hour difference.
