1. A police man spots a mugger from a distance of 200 meters. As the police man starts chasing the mugger, the mugger also starts 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?
- A. 3 km
- B. 3 km
- C. 3 km
- D. 3 km
Answer: Option D
Explanation:
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.
