A man is standing in a park facing north. He turns \(90^\circ\) left and walks 40 Km.
A man is standing in a park facing north. He turns \(90^\circ\) left and walks 40 Km. He again turns \(90^\circ\) right and walks 50 km. He again turns \(90^\circ\) right and walks 60 km. Finally, he turns \(90^\circ\) right and walks 50 km. How far is he from the starting point?
एक व्यक्ति पार्क में उत्तर की ओर अभिमुख होकर खड़ा हैं। वह बायीं ओर \(90^\circ\)मुड़ता है और 40 Km चलता है। वह फिर से दाहिनी ओर \(90^\circ\) मुड़ता है और 50 km चलता है। वह फिर से \(90^\circ\) दाहिनी ओर मुड़ता है और 60 km चलता है। अंत में, वह दायी ओर \(90^\circ\) मुड़ता है और 50 km चलता है। वह आंरभिक बिंदु से कितनी दूरी पर है?
Detailed Solution & Logic
20 km
- North की ओर खड़ा था
- 90° left → West, 40 km चला
- 90° right → North, 50 km चला
- 90° right → East, 60 km चला
- 90° right → South, 50 km चला
अब position निकालते हैं:
Horizontal (East–West):
- West = 40 km
- East = 60 km👉 Net = 20 km East
Vertical (North–South):
- North = 50 km
- South = 50 km👉 Net = 0
Final Distance:
👉 केवल East direction में 20 km
Final Answer:
👉 20 km ✔️
