Question : Directions: Rohan walks a distance of 3 km towards the north, then turns to his left and walks for 2 km. He again turns left and walks for 3 km. At this point, he turns to his left and walks for 3 km. How far is he from the starting point?
Option 1: 5 km
Option 2: 3 km
Option 3: 2 km
Option 4: 1 km
Correct Answer: 1 km
Solution :
Firstly, we will draw the diagram as per the given instructions –
Now, we have to find the distance between starting and endpoints.
In the above figure, O is the starting point and D is the finishing point. So, OD is the distance from the starting point.
OD = CD – OC (OC = AB = 2)
OD = 3 – 2
OD = 1 km
So, the distance from the starting point is 1 km. Hence, the fourth option is correct.
