Consider the following statements:

1. Every 15° of longitude is considered a one-time zone globally.

2. East-west stretch countries have more time zones than north-south ones.

3. The places in the west are advance in time than the places in the east.

The correct statement/s is/are:

Analysis of the Statements1. 15° of longitude equals one time zone (Correct)The Earth completes one full rotation of 360° in approximately 24 hours. By dividing the total degrees by the total hours ($360 \div 24$), we find that the Earth rotates 15° every hour. Therefore, each standard time zone globally is theoretically designed to cover 15° of longitude.2. East-west stretch vs. North-south stretch (Correct)Time zones change as you move along lines of longitude (East to West).Countries with a large East-West stretch (like Russia, USA, or Canada) cross many 15° intervals, necessitating multiple time zones to ensure that "noon" (the time when the sun is highest) roughly aligns with 12:00 PM across the country.Countries with a primarily North-South stretch (like Chile or Vietnam) stay within the same longitudinal bands and usually require only one time zone, regardless of how "long" they are from top to bottom.3. West is "advance" in time (Incorrect)The Earth rotates from West to East. This means that places in the East see the sun first and are "ahead" or advanced in time compared to the West.Example: Japan (the "Land of the Rising Sun") is ahead of India, and India is ahead of London (Greenwich). If it is 12:00 PM in London, it is already 5:30 PM in India.
