A thief is noticed by a policeman from a distance of 200 m. The thief starts running and the policeman, chases him. The thief and the policeman run at rate of 10 km/h and 11 km/h, respectively. The distance between them after 6 min will be ?
-
- 100 m
- 180 m
- 150 m
- 125 m
Correct Option: A
Relative speed of policeman with respect to thief = ( 11 - 10 ) = 1 km/h.
Now, relative distance covered by policeman in 6 min = Speed x Time
= (1 x 6)/60 = 1/10 km = 100 m
The distance between the policeman and thief after 6 min = (200 - 100) = 100 m
