Question 1
Two persons A and B start from the same point. A walks 19 m West, then 12 m North, then 13 m South. B walks 16 m North, then 20 m East, then 13 m South. What is the distance between them?
Step-by-step:
1. A's final position: (-19, -1)
2. B's final position: (20, 3)
3. Distance = √[(-19-20)² + (-1-3)²] = √[-39² + -4²] = 39 m
1. A's final position: (-19, -1)
2. B's final position: (20, 3)
3. Distance = √[(-19-20)² + (-1-3)²] = √[-39² + -4²] = 39 m
