Question 1356Navigation General70% to pass
A great circle crosses the equator at 127°W. It will also cross the equator at what other longitude?
AI Explanation
The correct answer is D) 53°E.
A great circle is the shortest distance between two points on the Earth's surface, and it crosses the equator at two points that are 180 degrees apart in longitude. Since the great circle crosses the equator at 127°W, it will also cross the equator at the opposite longitude, which is 53°E (127°W + 180° = 53°E).
The other options are incorrect because:
A) 27°W is not the opposite longitude of 127°W.
B) 27°E is not the opposite longitude of 127°W.
C) 127°E is not the opposite longitude of 127°W.
