    D) 250 m/s

    Correct Answer: A

    Solution :

    The relative velocity of thief's jeep with respect to police jeep \[=153-45\] \[=108\text{ }km/h\] \[=108\times \frac{5}{18}\] \[=30m/s\] Therefore, striking speed = relative speed of bullet with respect to thief's car \[=180-30\] \[=150m/s\]
