$$ \begin{cases} 1\ut{mile}&=1609\ut{m}\\ 1\ut{nautical~mile}&=1852\ut{m}\\ \end{cases} $$ $$ \begin{aligned} \Ans&=45.3\ut{nautical~mile}-45.3\ut{mile}\\ &=45.3(1\ut{nautical~mile}-1\ut{mile})\\ &=45.3(1852\ut{m}-1609\ut{m})\\ &=45.3\times243\ut{m}\\ &=11007.9\ut{m}\\ &\approx11.0\ut{km} \end{aligned} $$
