A river is flowing from west to east direction with speed of $\displaystyle 9 \mathrm{~km} \mathrm{~h}^{-1}$. If a boat capable of moving at a maximum speed of $\displaystyle 27 \mathrm{~km} \mathrm{~h}^{-1}$ in still water, crosses the river in half a minute, while moving with maximum speed at an angle of $\displaystyle 150$° to direction of river flow, then the width of the river is :
