A police traveling at 65 km/hr is chasing a thief who is 1200 m away from him and he is traveling at 41 km/hr. Find the time taken by the policeman to catch the thief.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3 min.
Policeman's speed = 65 km/hr
Thief's speed = 41 km/hr
Relative speed = 65 - 41 = 24 km/hr
Distance = 1200 m = 1200/1000 km = 1.2 km
Time required = 1.2/24 = 0.05 hours = (0.05 × 60) minutes = 3 minutes
Therefore, it will take the policeman 3 minutes to catch the thief.
