ECZ 2026 · GCE Paper 1 — Earth Geometry
In the diagram, NS is the Prime Meridian. The positions of towns A and B are (30°S, 30°W) and (30°N, 30°W) respectively. Find the distance between A and B in nautical miles.
- A. 1800 nautical miles
- B. 3600 nautical miles
- C. 60 nautical miles
- D. 3118 nautical miles
Verified working — step 1
A and B share longitude 30°W, so they lie on the same meridian - a great circle. Along a great circle 1° = 60 nautical miles, so find the angle between them first.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
