Convergency and conv angles
Hi there. I have a question that need some explanation.
The following 3 positions are given:
A) 0238N 17832E
B) 0317N 17615W
C) 0249S 17905W
Q1 - What is ch lat B - C?
Q2 - What is d long A - B?
Q3 - . A, B and C represent islands forming the HARRY ISLANDS.
A group of tourists is chartering a plane to take them to THE WESTERN HARRY ISLAND. To which of the islands would you take them?
What is the formula for finding change of latitude (Q1) and what are they looking for in Q2? Answers should be given in degrees and minutes.
My book says Convergency = Change of Longitude x Sine Latitude, but I donīt even know where to start :-/
