A man walks 3 km east, 4 km north, 3 km west. Distance from start? MCQ with Answer and Explanation

Explanation:
A to B north 10, B to C east 15, C to D south 10. So D is exactly 15 m east of A. Distance = 15 m.

Explanation:
East-west cancel, 11 km north.

Explanation:
Total east = 3+12=15, north 4 -> √(15²+4²)=√241 ≈ 15.52, not 13. I'll do 5 east, 12 north -> 13. So: 5 m east, then 12 m north. Shortest distance 13 m. So question: A child walks 5 m east, then 12 m north. Shortest distance? 13 m.
