Question 1
Two persons A and B start from the same point. A walks 16 m North, then 19 m South, then 11 m East. B walks 7 m East, then 11 m South. What is the distance between them?
Step-by-step:
1. A's final position: (11, -3)
2. B's final position: (7, -11)
3. Distance = √[(11-7)² + (-3--11)²] = √[4² + 8²] = 9 m
1. A's final position: (11, -3)
2. B's final position: (7, -11)
3. Distance = √[(11-7)² + (-3--11)²] = √[4² + 8²] = 9 m
