A Hrb = 14-00 en situación l =35º 50´ N L = 006º 10´ W navegamos al Rv = 060º y Vhb = 6 nudos. Situación a HRB= 17-00At ship's time 14-00 at l = 35º 50'N L = 006º 10'W we sail on true course 060º at speed 6 knots. Position at ship's time 17-00
Show the answer
Correct answer: b) l = 35º 59.0'N and L = 005º 51.0'W
Why it is correct
3 h at 6 knots is 18 miles. On 060: 18 × cos 60 = 9′ north, and 18 × sin 60 = 15.6 miles east, about 19.3′ of longitude.
Why the others are not
- a) Too much latitude and too little longitude.
- c) Too much latitude.
- d) Too much latitude and too little longitude.
How to work it out in the exam
- First distance = speed × time. Then plot and measure.
