What is the time difference between two places located at 60°E and 30°W?
Step 1: Identify the longitudes of the two places. One is at 60°E and the other is at 30°W.
Step 2: Convert the west longitude (30°W) to a positive value for calculation. This means we treat it as 30° east of the Prime Meridian, so we have 60°E and 30°E.
Step 3: Add the two longitudes together to find the total difference. Calculate 60° + 30° = 90°.
Step 4: Understand that the Earth is divided into 360 degrees of longitude, and each 15 degrees corresponds to a 1-hour time difference.
Step 5: Divide the total degree difference by 15 to find the time difference in hours. Calculate 90° / 15° = 6 hours.
