Siendo la situación inicial l=36º05´N y L=006º15´W y la final l=34º32´N y L=009º46´W, hallar el rumbo directo y la distancia entre ambas posiciones.With initial position l=36º05´N and L=006º15´W and final l=34º32´N and L=009º46´W, find the direct course and distance between them.
Show the answer
Correct answer: a) R= 241.6º d=196´.
Why it is correct
Δlat = 93′ S. Departure = 211′ × cos 35º18′ = 172′ W. Course 241.6º, 196 miles.
Why the others are not
- b) It does not match the working.
- c) 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.
