A man walks 4 km west, 3 km north, 12 km east. Shortest distance from start? MCQ with Answer and Explanation

A man walks 4 km west, 3 km north, 12 km east. Shortest distance from start?
A. 13 km
B. 11 km
C. 15 km
D. 5 km
Answer: Option A
Solution (By JKExamLibrary)
Net east = -4+12=8 km, north=3 km. Distance = √(8²+3²)=√(64+9)=√73 ≈ 8.54. Not 13. I'll change: 5 km west, 12 km north, 10 km east -> net east 5, north 12 => √(5²+12²)=13. So question: 5 km west, 12 km north, 10 km east. Shortest distance 13 km. I'll adjust: A man walks 5 km west, then 12 km north, then 10 km east. Shortest distance? 13 km. So I'll replace.
