PDE Q10
- Option : C
- Explanation :
The correct answer is:
C. 24 time zones
-
The Earth takes 24 hours to complete one rotation of 360 degrees.
-
Hence, the world is divided into 24 standard time zones, each covering roughly 15 degrees of longitude (since 360° ÷ 24 = 15° per hour).
-
Each time zone represents one hour difference from its neighboring zones.
That is why we generally say there are 24 time zones around the world.
