Answer 1

Answer:

Effective speed of bullet is  = Speed of bullet+Speed of police jeep

                                              =180m/s+45 km/hr

                                              =180+45×

​

m/s

                                              =192.5m/s

Speed of thief's jeep =153 km/hr=42.5m/s

Velocity of bullet with respect to thief's jeep =192.5−42.5m/s

                                                                          =150m/s
