Question 1894Navigation General70% to pass
A great circle crosses the equator at 134°E. It will also cross the equator at what other longitude?
AI Explanation
The correct answer is B) 46°W.
A great circle is the shortest distance between any two points on the Earth's surface. Since a great circle crosses the equator at two points, the second point must be 180 degrees, or half a circle, away from the first point. Since the great circle crosses the equator at 134°E, the second crossing point must be at 134°W, which is 180 degrees away.
The other options are incorrect because: A) 124°W is not 180 degrees away from 134°E, C) 134°W is the same as the first crossing point, and D) 34°E is not 180 degrees away from 134°E.
