Understanding Ravi's Movement
Ravi's journey can be visualized on a coordinate plane, starting from an initial point (0, 0). Let's break down his movements step by step:
Step 1: Walking West
- Ravi walks 4 km west.
- This means he moves from (0, 0) to (-4, 0).
Step 2: Turning South
- Next, he turns south and walks 3 km.
- His new position is now (-4, 0) to (-4, -3).
Step 3: Turning East
- Finally, he turns east and walks 8 km.
- This takes him from (-4, -3) to (4, -3).
Calculating the Minimum Distance
To find the minimum distance between his initial position (0, 0) and final position (4, -3), we can use the distance formula. The formula for distance between two points (x1, y1) and (x2, y2) is:
- Distance = √((x2 - x1)² + (y2 - y1)²)
Plugging in the points:
- Distance = √((4 - 0)² + (-3 - 0)²)
- Distance = √(4² + (-3)²)
- Distance = √(16 + 9)
- Distance = √25
- Distance = 5 km
Conclusion
The minimum distance between Ravi's initial position and final position is 5 km, confirming that the correct answer is option 'B'.
