Question 1899Navigation General70% to pass
The vertex of a great circle track is in LONG 109°E. An eastbound vessel would cross the equator in LONG _______________.
AI Explanation
The correct answer is D) 161°W.
The vertex of a great circle track is the point where the great circle track crosses a meridian at its highest or lowest latitude. Since the vertex is at LONG 109°E, the great circle track would cross the equator at the opposite side of the earth, which is LONG 161°W.
The other options are incorrect because:
A) 19°W is not the opposite side of the earth from the vertex at 109°E.
B) 161°E is not the opposite side of the earth from the vertex at 109°E.
C) 19°E is not the opposite side of the earth from the vertex at 109°E.
