Question 1
A person starts from point O and walks 21m South, then 14m South, then 17m West. What is his straight line distance from point O?
Step-by-step:
1. Track movements: 21m South, then 14m South, then 17m West
2. Net position: (-17, -35)
3. Distance = √(-17² + -35²) = √1514 = 39 m
1. Track movements: 21m South, then 14m South, then 17m West
2. Net position: (-17, -35)
