Question : Directions: Rocky starts from point A and drives 3 km towards the east. He takes a left turn and drives 4 km. He again takes a left turn and drives 3 km. He takes one more left turn and then drives 2 km and stops at B. How far and towards which direction should he drive to reach point A again?
Option 1: 2 km towards the south
Option 2: 3 km towards the south
Option 3: 3 km towards the east
Option 4: 2 km towards the north
Correct Answer: 2 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 = 3 km; CD = 4 km; DE = 3 km; EB = 2 km
Now, find the distance between the starting point and the endpoint –
AB = CD – EB = 4 – 2 = 2 km
So, Rocky should drive 2 km towards the south to reach point A. Hence, the first option is correct.
