  • A 90\(^o\) W
  • B 180\(^o\) E
  • C 150\(^o\) W
  • D 80\(^{o}\) E
Correct Answer: Option 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
