Question

A thief steals a car at 3 am and riding at a speed of 60 km/hr. Theft was found at 4.30 am and police started chasing him at a speed of 75 km/hr. At what time the police will catch the thief?

Answer 1

Answer:

Distance travelled by thief from 03:00 am to 04:30 am (in 1.5 hours)= 1.5*60 =90 km

After 04:30 am, relative velocity between police and thief=75-60 = 15km/hr

So time taken = distance/speed = 90/15 = 6 hour

so police will catch the thief at 10.30 am (assuming everything happens alright :)
