Coordinates (turns and distances): Compute Reena's distance from the starting point A. Path: A → B (east) 10 ft; turn right and walk 3 ft; turn right again and walk 14 ft. Find the straight-line distance from her final position back to A.

Difficulty: Easy

Correct Answer: 5 feet

Explanation:


Given data & path
East 10 ft → Right (south) 3 ft → Right (west) 14 ft.


Concept/Approach
Resolve net displacement (x, y) and apply the Pythagoras theorem.


Step-by-step
Net x = +10 − 14 = −4 ft (4 ft west)Net y = −3 ft (3 ft south)Distance = √(4² + 3²) = √(16 + 9) = √25 = 5 ft


Final Answer
5 feet
