Someone gets on an airplane in Greenwich, england. they fly forward in time six hours. After 6 hours forward flight they would be at longitude 90° eastward.
The Greenwich is at Longitude 0 degrees, for a trip ahead in time indicates that the Flight direction is eastward.
Every location on Earth was calculated based on how far it was to the east or west of this line. The line itself separated the eastern and western halves of the planet, just like the equator does for the north and south.
The Longitude line, which runs from the north pole to the south pole, cuts the world in half at an angle of 180° to the east and 180° to the west of the equator.
The world is split into 24 hours, each longitude is 15° apart from the one that is nearest ( 12 hours to the east and 12 hours to the west )
e.g., 15° = 180° / 12 hours
As a result, after six hours of forward motion, their longitude would be
15° * 6 hours, or 90° east.
As a result, we may infer that they would be 90° east of longitude.
