a thief is ascaping with avelocity of 54km/h and the policeman follows him with 72km/h. if the gap b/w the policeman and the thief is 10km/h . how much time the thief will be caught​

Answer 1

Answer:

Relative Velocity of the Policeman = (72 - 54) km/hr

                                                          = 18 km/hr

                                                          = 5 m/s

∴ Time required = 10000/5 s

                           = 2000 s

                           =33 mins. 20 seconds.
