70% to passA great circle crosses the equator at 93°W. It will also cross the equator at what other longitude?
A
13°E
B
177°E
C
87°E
D
177°W
AI Explanation
The correct answer is C) 87°E. A great circle is the shortest distance between two points on the Earth's surface, and it will cross the equator at two points that are 180 degrees apart in longitude. Since the great circle crosses the equator at 93°W, the other point where it will cross the equator must be 180 degrees away, which is 87°E. The other options are incorrect because: A) 13°E is not 180 degrees away from 93°W. B) 177°E is not 180 degrees away from 93°W. D) 177°W is not 180 degrees away from 93°W.
