Question 1
Two persons A and B start from the same point. A walks 10 m South, then 5 m North. B walks 14 m West, then 18 m West. What is the distance between them?
Step-by-step:
1. A's final position: (0, -5)
2. B's final position: (-32, 0)
3. Distance = √[(0--32)² + (-5-0)²] = √[32² + -5²] = 32 m
1. A's final position: (0, -5)
2. B's final position: (-32, 0)
3. Distance = √[(0--32)² + (-5-0)²] = √[32² + -5²] = 32 m
