Speed of the police van vp = 30 km/h = 8.33 m/s
Muzzle speed of the bullet vb = 150 m/s
Resultant speed of bullet will be
vb' = vp+vb
vb' = 150 + 8.33 
vb' = 158.33 m/s

Hii dear,
# Answer- 105m/s
# Given-
Speed of the police van vp = 30 km/h = 8.33 m/s
Muzzle speed of the bullet vb = 150 m/s
Speed of the thief’s car vt = 192 km/h = 53.33 m/s
# Solution-
Resultant speed of bullet will be
vb' = vp+vb
vb' = 150 + 8.33 
vb' = 158.33 m/s
Relative velocity of bullet in regard to thief's car is
vbt = vb – vt
vbt = 158.33 – 53.33
vbt = 105 m/s
Hence, bullet will hit the thief's car at the speed of 105 m/s.
