¿Cuál sería el rumbo y distancia entre los puntos A (l= 35º40´N; L= 006º25W) y B (l= 34º40´N; L= 005º25´W), en dirección de A a B?What would be the course and distance between A (l= 35º40´N; L= 006º25W) and B (l= 34º40´N; L= 005º25´W), going from A to B?
Show the answer
Correct answer: c) Course: 140.7º / Distance: 77.5 miles.
Why it is correct
Δlat = 60′ S. Departure = 60′ × cos 35º10′ = 49′ E. Course S 39.3º E, or 140.7º, and 77.5 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.
