En situación l = 35º-40,0’ N, L = 005º-32,0’ W nos dirigimos a un punto de l = 36º-05,0´ N, L = 004º-44,0’ W. Calcular la distancia entre los dos puntos.At l = 35º-40.0’ N, L = 005º-32.0’ W we head for a point at l = 36º-05.0´ N, L = 004º-44.0’ W. Calculate the distance between the two points.
Show the answer
Correct answer: c) Dist = 46.30 miles.
Why it is correct
Δlat = 25′. Departure = 48′ × cos 35º52′ = 38.9′. Distance = √(25² + 38.9²) = 46.2 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
- Find the difference of latitude and the departure: ΔL × cos(mean latitude).
- Course = arctan(A / Δlat). Distance = root of the sum of squares.
