Use the following English and metric equivalents, along with dimensional analysis, to convert the given measurement to the unit indicated.English and Metric Equivalents$$\begin{aligned}&1 \text { in. }=2.54 \mathrm{~cm} \\\&1 \mathrm{ft}=30.48 \mathrm{~cm} \\\&1 \mathrm{yd} \approx 0.9 \mathrm{~m} \\\&1 \mathrm{mi} \approx 1.6 \mathrm{~km}\end{aligned}$$ \(265 \mathrm{mi}\) to \(\mathrm{km}\)
Determine whether each statement makes sense or does not make sense, and explain your reasoning. The most frequent use of dimensional analysis involves changing units within the metric system.
In Exercises 53-54, use the unit fractions \(\frac{5280 \mathrm{ft}}{1 \mathrm{mi}}, \frac{12 \mathrm{in} .}{1 \mathrm{ft}}\), and \(\frac{2.54 \mathrm{~cm}}{1 \mathrm{in} .}\). Convert \(30 \mathrm{mi}\) to \(\mathrm{km}\).
