A and B start from point X. A goes 5 km north, then 12 km east. B goes 13 km east directly. Distance between A and B:
A5 km
B8 km
C12 km
D13 km
Answer & Solution
Correct answer: A. 5 km
1. A is at (12, 5) after 5 km N + 12 km E.
2. B is at (13, 0) after 13 km E.
3. Distance = √((13-12)² + (0-5)²) = √(1 + 25) = √26 ≈ 5.1; closest 5 km.
