A thief steals a car at 2.30pm and drives it at 60km/hr . The theft is discovered at 3pm and the owner sets off in another car at 75km/hr. When will he overtake the thief ?

Answer»

5PM



Distance TRAVEL by thief in 1/2 hours = 60 * 1/2 = 30km
Relative speed of owner = 75 - 60 = 15km/hr
 Time REQUIRED = 30/15 = 2hours
Starting counting 2hours from 3pm, thief will be caught at 5pm
