Q. Kunal walks 10 km towards the North. From there he walks 6 km towards the South. Then, he walks 3 km towards the East. How far and in which direction is he with reference to his starting point?
- 5 km West
- 7 km West
- 7 km East
- 5 km North-east
EXPLANATION
Clearly, Kunal moves from A 10 km north-wards up to B, then moves 6 km southwards up to C, turns towards East and walks 3 km up to D. Then, AC = (AB – BC) = (10 – 6) = 4 km. So, Kunal’s distance from the starting point A.
Also, D is to the North-east of A.
Hence, option D is correct.
