Rakesh walks 50 km towards East. He then turns right and then walk 15 ...
To solve this problem, we need to visualize Rakesh's movements on a coordinate plane. Let's break down his movements step by step:
1. Rakesh walks 50 km towards East.
- Starting from the origin (0,0), he moves 50 km to the right in the positive x-direction. His new position is (50,0).
2. Rakesh turns right and walks 15 km.
- After turning right, he walks 15 km in the positive y-direction. His new position is (50,15).
3. Rakesh turns right again and walks 50 km.
- Now, he turns right again and walks 50 km in the negative x-direction. His new position is (0,15).
4. Rakesh moves 10 km after turning right.
- Finally, he moves 10 km in the negative y-direction. His new position is (0,5).
Now, we can use the distance formula to find the distance between his final position and the origin:
Distance = √((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the values, we get:
Distance = √((0 - 0)^2 + (5 - 0)^2)
Distance = √(0 + 25)
Distance = √25
Distance = 5 km
Therefore, Rakesh is 5 km away from his original position. Hence, the correct answer is option D.

Rakesh walks 50 km towards East. He then turns right and then walk 15 ...
1st :- 50km towards east
2nd:- he turns right means south - 15km
3rd :- than at south to West he walk 50 km that is some distance he covered at first from West to east
4th :- that from south West he turns right nd walk 10km that means he is in west
solution :- as we see he start from north to east -50 km
and from north to South- 15 km . so distance from the original place that was north and now he is at west .....so if distance best N nd S is 15km than distance between W and N is
15 - 10= 5 that is the answer
hope you could understand the concept
