Effective speed of bullet is $=$ Speed of bullet + Speed of police jeep $$\begin{aligned} & =18 \mathrm{om} / \mathrm{s}+45 \mathrm{~km} / \mathrm{hr} \\ & =180+45 \times \frac{5}{18} \mathrm{~m} / \mathrm{s} \\ & =192.5 \mathrm{~m} / \mathrm{s} \end{aligned}$$) Speed$of$theifs jeep (=153 \mathrm{~km} / \mathrm{hr}=42.5 \mathrm{~m} / \mathrm{s}) Velocity of bullet with respect to theif's jeep (=192.5-42.5 \mathrm{~m} / \mathrm{s}) (=150 \mathrm{~m} / \mathrm{s})$
