What is the time difference between two places located at longitudes 30°E and 90°E? (2021)

Step 1: Identify the longitudes of the two places. One is at 30°E and the other is at 90°E.
Step 2: Subtract the smaller longitude from the larger longitude. So, calculate 90°E - 30°E.
Step 3: The result of the subtraction is 60°. This means there is a 60° difference in longitude.
Step 4: Understand that the Earth is divided into 24 time zones, and each time zone corresponds to 15° of longitude.
Step 5: To find the time difference, divide the longitude difference (60°) by the degrees per time zone (15°). So, calculate 60° / 15°.
Step 6: The result of the division is 4. This means the time difference between the two places is 4 hours.
