Show the answer
Correct answer: d) l = 35º 59.2' N; L = 005º 45.3' W.
Why it is correct
If Punta Paloma (36º 04.0′ N, 005º 43.2′ W) bears 020º true, the vessel lies along the reciprocal bearing 200º from the light. Measuring 5 miles along 200º from Punta Paloma gives l = 35º 59.2′ N, L = 005º 45.3′ W.
Why the others are not
- a) Does not match measuring 5 miles along 200º true from Punta Paloma.
- b) Does not match measuring 5 miles along 200º true from Punta Paloma.
- c) Does not match measuring 5 miles along 200º true from Punta Paloma.
How to work it out in the exam
- Compute the reciprocal bearing from Punta Paloma: 020º + 180º = 200º.
- Measure 5 miles along 200º from Punta Paloma: 35º 59.2′ N, 005º 45.3′ W.
