A thief is noticed by a policeman from a distance of 500 m. The thief starts running, and the policeman chases him. The thief and the policeman run at speeds of 12 km/h and 13 km/h, respectively. What is the distance between them after 12 minutes?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 300 m.
Relative speed = 13 - 12 = 1 km/hr
Time = 12 minutes = 12/60 = hours
Distance = × 1 = km = 200 m
Distance after 12 minutes = 500 - 200 = 300 m
