Question 1
Two persons A and B start from the same point. A walks 6 m West, then 9 m West. B walks 16 m East, then 9 m West. What is the distance between them?
Step-by-step:
1. A's final position: (-15, 0)
2. B's final position: (7, 0)
3. Distance = √[(-15-7)² + (0-0)²] = √[-22² + 0²] = 22 m
1. A's final position: (-15, 0)
2. B's final position: (7, 0)
3. Distance = √[(-15-7)² + (0-0)²] = √[-22² + 0²] = 22 m
