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 the speed of 10 km/h and 11 km/h respectively. What is the distance between them after 6 minutes?

100 m

Relative speed = ( 11 - 10 ) = 1 km/h = \(\frac{5}{18}\) m/sec

Distance covered in 6 minutes = \(\frac{5}{18}\) × 6 × 60 = 100m

Distance b/w thief and policeman after 6 minutes  = 200 - 100 = 100m

The correct answer is Option (1) → 100 m
