Ram travels a distance of 5 km from a place A towards north, and then turns left and walks 3 km, again turns right and walks 2 km. Finally, he turns right and walks 3 km to reach the place B. What is the distance between A and B?
-
A.
7 km
-
B.
13 km
-
C.
10 km
-
D.
2 km
Correct Answer:
A. 7 km
Explanation:
To determine the distance between point A and point B, we can track Ram's movements step by step: - Initial Movement: Ram travels 5 km North from point A.
- Second Movement: He turns left (West) and walks 3 km.
- Third Movement: He turns right (North) and walks another 2 km.
- Final Movement: He turns right (East) and walks 3 km to reach point B.By analyzing the East-West movement, the 3 km walk to the West is exactly cancelled out by the final 3 km walk back to the East. This means point B is directly North of point A.
To find the total distance, we add the vertical components: the initial 5 km North and the subsequent 2 km North. Therefore, the total distance between A and B is 7 km.
