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?

Answer 1

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
