A railway engine starts shunting wagons by first going 1000 m North of railway station. It reverses and travels 1250 m South and then it again moves 600 m north. Finally moving 800 m South it comes to rest. How far is the engine from the station and in which direction?

Answer 1

1250-1000 = 250 m south
600-250 = 350 m north
800-350 = 450 m south

So it is 450 m south of station
