What is the difference in longitude between P (lat. 50°N. long. 50°W) and Q (lat.50°N, long. 150°W)?

  • A.
    300o
  • B.
    200o
  • C.
    130o
  • D.
    100o
  • E.
    30o
Correct Answer: Option D
Explanation

Let (theta) be the angular difference between P (50°N. 50°W), and Q (50°N, 150°W),
(theta) = 150° – 50° =100°
