Solution :
Here , according to the information given about the positions of Aamir, we need to find how far he is from his starting point.
Let us for the sake of conveyance take his starting point as the origin and the directions in the term of that.
Thus, East is represented by positive x axis
West is represented by negative x axis.
North is represented as positive y axis .
South is represented as negative y axis .
He moves 3 km to the east.
His position - (3,0 )
He travels 6 km north
His position - (3,6)
He now goes 5 kms east
His final position :( 8, 6)
Distance from the origin :
> square root of (Abcisssa)^2 + (Ordinate)^2
> root (64 + 36 )
> 10 km.
This is the required answer,
