A person is swimming with a speed of $\displaystyle 10 \mathrm{~m} / \mathrm{s}$ at an angle of $\displaystyle 120^{\circ}$ with the flow and reaches to a point directly opposite on the other side of the river. The speed of the flow is '$\displaystyle x$' $\displaystyle \mathrm{m} / \mathrm{s}$. The value of ' $\displaystyle x$ ' to the nearest integer is \_\_\_\_.
