One day, Amit left home and cycled 15 km southwards, turned right and cycled 7 km and turned right and cycled 10 km and turned left and cycled 5 km. How many kilometres will he have to cycle to reach his home?
Explanation
1. Amit ki Movement ka Mathematical Breakdown
Amit ke har move ko coordinates mein convert karte hain:
-
Starting Point (Home): A=(0,0)
-
15 km South: Amit niche ki taraf gaya.
-
7 km Right (Turning South se Right matlab West):
-
10 km Right (Turning West se Right matlab North):
-
5 km Left (Turning North se Left matlab West):
2. Home (0,0) tak Pahunchne ke liye Distance (d)
Amit ab point E(−12,−5) par hai. Usse ghar (0,0) wapas jana hai.
Distance Formula ka use karte hain:
3. Conclusion
Amit ko apne ghar pahunchne ke liye 13 km cycle chalani hogi.
