Answer 2

Shyam is 10 km, West of the school.

• The journey of Shyam is shown below in the attached picture.
• He moves north and then turns left. While facing north, the west lies to the left so he has turned to the west.
• After walking 10km in the west direction he again turns left. The south direction lies on the left. So he moves towards the south direction.
• This path is a rectangle now. Since the opposite sides are equal in length, we can infer that the distance between the final and the initial point is 10km.
