Answer :
Speed of thief = 10 km/h
speed of police = 15 km/h
relative speed = speed of police - speed of thief = 15-10 = 5 km/h
distance between them = 500m = 0.5 km
time taken = [tex] \frac{distance}{relative\ speed}= \frac{0.5}{5}=0.1\ hour=0.1 \times 60=6minutes[/tex]
So the police will take 6 minutes to catch the thief.
