Questions & Step-by-Step Solutions
If a place is located at 120°W longitude, what is its time difference from GMT?
Step 1: Understand that the Earth is divided into 360 degrees of longitude.
Step 2: Know that each 15 degrees of longitude corresponds to a 1-hour difference in time.
Step 3: Identify that 120°W means the location is west of the Prime Meridian (0° longitude).
Step 4: Calculate the time difference by dividing 120 by 15 (120° / 15° = 8).
Step 5: Since 120°W is west of GMT, the time difference is -8 hours.
