Question

# A theif running on a train with 12km/h . The police car moving with 80 km/h . If the speed of the train is 60 km/h .what is the speed of theif w.r.t police car?

Solution

## Speed of the police car=80km/hr Speed of train=60km/hr Speed of thief on the train=12km/hr Therefore,speed of the thief=60+12km/hr                                                                                          =72km/hr Hence,speed of the thief w.r.to  police car =72-80                                                                                                                                       =-8km/hr since speed cant be negative this  means speed of the thief is less than the police car. hope it helps frnd
