Consider the following statements: I. The Prime Meridian is the same as the International Date Line. II. West of the International Date Line is always a day later than east of the line. III. The Earth turns 15° of longitude in an hour. Which of the statements given above is/are correct?
II and III only
Statement I is incorrect: the Prime Meridian (0° longitude, Greenwich) and the International Date Line (roughly 180° longitude) are two entirely different reference lines. Statement II is correct: since clocks run progressively ahead moving eastward up to the Date Line, crossing it from east to west advances the calendar by one day, so places just west of the line are always a day later than places just east of it. Statement III is correct: the Earth completes one 360° rotation in 24 hours, so it turns 360/24 = 15° of longitude every hour. Hence, only statements II and III are correct.
