Question

What happens when Sid sailing at 180 degree longitude move ________, he will _______.

• A. move back a day
• B. move a day ahead
• C. have same date

Answer 1

If Sid is travelling to East from 180 degree line, then he will be entering the other hemisphere which is back by a day and if the converse is happening that means, if he is moving towards West from East then he will move a day ahead from his current date. If he travels parallel to the 180 degree longitude then he will have same date.
