Answer 1

Velocity of police vp=30km/h=325m/s

Velocity of thief vt=190km/h=3160m/s

Velocity of bullet which police is fire vb=150m/s

final velocity of bullet muzzle from gun =vb+vp=150+325=3475m/s

Let velocity of thief is Zero and seen with respect to thief. velocity of bullet w.r.t thief 

vb/t=vb−vt=3475−3160=3315= 105m/s
