¿Cuál de las siguientes respuestas más se aproxima al Rumbo directo y distancia entre los puntos A (l= 43º49´N; L= 007º54’W) y B (l= 43º40’N; L=001º55’W)?Which answer is closest to the direct course and distance between A (l= 43º49´N; L= 007º54’W) and B (l= 43º40’N; L=001º55’W)?

Correct answer: c) Course= 092º / Distance= 258 miles.

Why it is correct

Δlat = 9′ S. Departure = 359′ × cos 43º44′ = 259′. Course 092º, about 259 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

1. Find the difference of latitude and the departure: ΔL × cos(mean latitude).
2. Course = arctan(A / Δlat). Distance = root of the sum of squares.
