Question 1
Two persons A and B start from the same point. A walks 6 m North, then 14 m South, then 9 m West. B walks 11 m West, then 10 m East, then 5 m North. What is the distance between them?
Step-by-step:
1. A's final position: (-9, -8)
2. B's final position: (-1, 5)
3. Distance = √[(-9--1)² + (-8-5)²] = √[-8² + -13²] = 15 m
1. A's final position: (-9, -8)
2. B's final position: (-1, 5)
3. Distance = √[(-9--1)² + (-8-5)²] = √[-8² + -13²] = 15 m
