Answer: 45°E
Step-by-step explanation:
The lines of longitude can be used to determine the time of an area.
Every 15° line of longitude away from the Prime Meridian is an extra hour away from the time at the Prime Meridian.
The Prime Meridian is GMT and is the 0° longitude.
Areas that are ahead of GMT are to the east of the Prime Meridian and those behind GMT are west.
If the time is 5am in place X and it is 2am in GMT, the time difference is:
= 5 - 2
= 3 hours
Place X is ahead of GMT so they are to the east of the Prime Meridian.
3 hours in degrees is:
= 3 * 15
= 45°
Place X is 45° east of the Prime Meridian so is labelled as 45°E.
