Type: MCQ • Marks: 1
A thief is spotted by a policeman from a distance of 200 m. The thief starts running and policeman chases him at speeds of 10 km/h and 11 km/h respectively. What distance will the thief cover before being caught?
Options
A. 1) 1000
B. 2) 1200
C. 3) 1500
D. 4) 2000
Explanation
Relative speed = 11 - 10 = 1 km/h. Time to catch = 0.2 km / 1 km/h = 0.2 h. Distance by thief = 10 km/h * 0.2 h = 2 km = 2000 meters.
