Explanation
All three statements are correct. Countries with large east-west extent like Russia (11 time zones), USA (multiple time zones), and Canada have adopted more than one standard time. The Earth is divided into 24 time zones of one hour each (since Earth rotates 360° in 24 hours). Each time zone covers 15° of longitude (360° ÷ 24 = 15°). Hence all three statements are correct.
