A child walks 2 km south, 2 km east, 2 km north. How far from start? MCQ with Answer and Explanation

Explanation:
South 10, left (east) 5, left (north) 10 -> net east 5 km.

Explanation:
N left 90° = West, right 180° = East? Wait: West (270°) + 180° = 90° East? Actually 270°+180°=450°=90° East. So East. Option B. I'll recalc: North -> left 90° -> West. Then 180° right from West: West (270°) +180° clockwise = 450° mod 360 = 90° East. So East. Answer East.

Explanation:
Total east = 3+12=15 km, north=4 km. Distance = √(15²+4²)=√(225+16)=√241 ≈ 15.52. Not matching. I'll do 3 east, 4 north, 12 east? No. I'll do: 5 km east, 12 km north -> 13. So: A car moves 5 km east, then 12 km north. Shortest distance from start? 13 km. Option A 13 km.
