Show the answer
Correct answer: c) 4484.6´
Why it is correct
It crosses the 180º meridian: ΔLong = 97º 31′. The formula gives about 4485 miles.
Why the others are not
- a) It does not match the working.
- b) It does not match the working.
- d) It does not match the working.
How to work it out in the exam
- cos D = sin l1 sin l2 + cos l1 cos l2 cos ΔL, with south latitude negative.
- Turn D into minutes: each minute is a mile.
