What is the time difference between two places located at 30°E and 30°W?
Step 1: Identify the longitudes of the two places. One is at 30°E and the other is at 30°W.
Step 2: Calculate the total angular distance between the two longitudes. This is done by adding the two values: 30°E + 30°W = 60°.
Step 3: Understand that the Earth is divided into 360 degrees of longitude, and it takes 24 hours for the Earth to complete one full rotation. This means that every 15 degrees of longitude corresponds to a 1-hour time difference.
Step 4: To find the time difference, divide the total angular distance (60°) by the number of degrees per hour (15°). So, 60° / 15° = 4 hours.
Step 5: Conclude that the time difference between the two places located at 30°E and 30°W is 4 hours.
