Question 1
A person starts from point O and walks 18m North, then 12m West, then 15m East. What is his straight line distance from point O?
Step-by-step:
1. Track movements: 18m North, then 12m West, then 15m East
2. Net position: (3, 18)
3. Distance = √(3² + 18²) = √333 = 18 m
1. Track movements: 18m North, then 12m West, then 15m East
2. Net position: (3, 18)
3. Distance = √(3² + 18²) = √333 = 18 m
