(S.R)^2 = (15)^2 + (6)^2
(S.R)^2 = 225 + 36
(S.R)^2 = 261
S.R = √261
S.R = 16.1 NM, So the answer is A
2nd : You have the compass and magnetic heading 190° and 188° respectively. Remember Variation east magnetic least (-) so in order to get true track you need to go east(-) because variation is 3°E from the magnetic track. Therefore 188°-3° = 185°(T). The deviation was east(-) of magnetic by 2° So, -2°
3rd : I think it's a question of 1 in 60 rule but not sure
The 1st answer was correct but the 2nd was wrong according to the question bank results
