Answer:
9:00 am
Explanation:
Lines of longitude are imaginary lines running from the north pole to the south pole of earth. These lines are used to calculate the time in places. Also when combined with lines of latitude, they are used to give the exact location of a place.
Given the place is at 45°W longitude and the time at GMT is 12:00 noon.
Degree difference = 0° (GMT) - 45° = -45°
1° = 4 min
time difference = -45° * 4 min per degree = -180 minutes = -3 hours
Therefore the local time at a place 45°W longitude = 12:00 noon - 3 hours = 9:00 am
