Question 1
From point P, a person walks 20 m West, then 21 m South. What is the shortest distance from point P?
Step-by-step:
1. These movements form a right angle
2. Shortest distance = √(20² + 21²)
3. = √(400 + 441) = √841 = 29 m
1. These movements form a right angle
2. Shortest distance = √(20² + 21²)
