Question : Directions: Rajesh drives 4 km towards the west from point A and then takes a right turn and drives 8 km. He again takes a right turn and drives 8 km. He again takes one more right turn and drives 4 km. Finally, he takes a right turn and drives 4 km to reach point B. How far and towards which direction should he drive to reach point A again?
Option 1: 3 km towards the north
Option 2: 2 km towards the east
Option 3: 4 km towards the south
Option 4: 4 km towards the west
Correct Answer: 4 km towards the south
Solution : Firstly, we will draw the diagram as per the given instructions –
Here, A is the starting point and B is the endpoint.
AC = 4 km; CD = 8 km; DE = 8 km; EF = 4 km; FB = 4 km
Now, find the distance between the starting point and the endpoint –
AB = CD – EF = 8 – 4 = 4 km
So, Rajesh should drive 4 km towards the south to reach point A. Hence, the third option is correct.
