ATPL General Navigation Question
Hi would anyone be able to help me with this question that our whole class are confused about?
A ground feature was observed on a relative bearing of 325° and five minutes later on a relative bearing of 280°. The aircraft heading was 165°(M), variation 25°W, drift 10°Right and GS 360 kt. When the relative bearing was 280°, the distance and true bearing of the aircraft from the feature was:
A. 30 NM and 240°
B. 40 NM and 110°
C. 40 NM and 290°
D. 30 NM and 060°
The correct answer is A but were unsure how you get the answer.
