Option 2: 30 m, South
Option 3: 30 m, North
Option 4: 40 m, North West
Correct Answer: 30 m, North
Solution : Firstly, we will draw the diagram as per the given instructions –
Here, Point A is Richa's home, i.e., her starting point, and Point B is her endpoint.
From the above diagram, the distance between the starting and the endpoint is 30 m and the endpoint is in the North direction from the starting point.
So, Richa is in the North direction and is at a distance of 30 m from the starting point. Hence, the third option is correct.
