A police man spots a mugger from a distance of 200 meters. As the police man starts chasing the mugger, the mugger also starts running. Given that the speed of the mugger is 10 km/h and that of the police man is 12 km/h, how far would have the mugger run before he is caught? Correct Answer 1 km

Lets say the mugger ran for T hours before being caught. 200 meters = 0.2 km ATQ,  12T = 10T + 0.2 Or,   12T - 10T = 0.2 Or,    T = 0.1 hour So, he ran = 10T = 10 x 0.1 = 1 km.
