Rahim walks 15 km towards North. From there he walks 9 km towards South. Then he walks 8 km towards East. How far and in which direction is he now from his starting point?
- a.7 km North-East
- b.10 km North-East
- c.10 km South-West
- d.7 km South-East
Answer: (B) 10 km North-East
Net movement is 15 − 9 = 6 km North and 8 km East. The straight-line distance is $\sqrt{6^2 + 8^2} = 10$ km, and he is north and east of the start, i.e. North-East. South-West reverses the direction.
