If a place is located at 120°W longitude, what is the time difference from GMT?

If a place is located at 120°W longitude, what is the time difference from GMT?

Step 1: Understand that the Earth is divided into 360 degrees of longitude.
Step 2: Know that each degree of longitude corresponds to a time difference of 4 minutes.
Step 3: Calculate the time difference by multiplying the degrees of longitude (120°) by the time per degree (4 minutes).
Step 4: Perform the calculation: 120° * 4 minutes = 480 minutes.
Step 5: Convert 480 minutes into hours by dividing by 60 (since there are 60 minutes in an hour).
Step 6: Perform the division: 480 minutes ÷ 60 = 8 hours.
Step 7: Since the location is at 120°W, it is 8 hours behind GMT.

Longitude and Time Zones – Understanding how longitude affects time zones, where each degree of longitude corresponds to a time difference of 4 minutes.
Greenwich Mean Time (GMT) – The reference point for time zones, where GMT is considered 0° longitude.
