What is the difference in longitude between P (lat. 50^\circN. long. 50^\circW) and Q (lat.50^\circN, long. 150^\circW)?
A
300o
B
200o
C
130o
D
100o
E
30o
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
Let \(\theta\) be the angular difference between P (50^\circN. 50^\circW), and Q (50^\circN, 150^\circW),
\(\theta\) = 150^\circ - 50^\circ =100^\circ
