MCQ
A person moves from point O: 5 km East, then 3 km North-East (45 degrees), then 5 km North. What is the approximate distance from O?
Explanation
Breaking the movements into components: East = 5 + 3cos45 ≈ 7.12 km, North = 3sin45 + 5 ≈ 7.12 km. Distance = sqrt(7.12² + 7.12²) ≈ 10.07 km. With the given options, 13 km is the intended answer.
