What is the longitude of a town Y whose local time is 12:00 noon when Greenwich mean time is 6:00pm
90\(^o\) W
180\(^o\) E
150\(^o\) W
80\(^{o}\) E
Correct answer is A
Town Y? W|12:00noon ←(substract) Longitude(0^o)|E 6:00pm
Time difference = 6:00pm - 12:00pm = 6hours
Recall: 15o ≡ 1 hour therefore 6hours ≡ (15 x 60)o= 90o
Arrow is pointing to the west;hence, the latitude of Town Y is 90oW
