Question 1
Two persons A and B start from the same point. A walks 20 m South, then 15 m North, then 8 m West. B walks 8 m East, then 5 m South, then 12 m South. What is the distance between them?
Step-by-step:
1. A's final position: (-8, -5)
2. B's final position: (8, -17)
3. Distance = √[(-8-8)² + (-5--17)²] = √[-16² + 12²] = 20 m
1. A's final position: (-8, -5)
2. B's final position: (8, -17)
3. Distance = √[(-8-8)² + (-5--17)²] = √[-16² + 12²] = 20 m
