B. 5 hours

C. 4 hours

D. 3 hours

Answer: Option D

Solution(By Examveda Team)

$$\eqalign{ & {\text{Time}} = \frac{{{\text{Distance}}}}{{{\text{Speed}}}} \cr & = \frac{{162}}{{15 \times \frac{{18}}{5}}}{\text{hr}} \cr & = \frac{{162 \times 5}}{{15 \times 18}}{\text{hr}} \cr & = 3{\text{ hrs}} \cr} $$
