Step-by-step explanation

From the statement, we know that the speed of the cheetah is:


S=1.73*(km)/(m\imaginaryI n).

We have the following ratios:


\begin{gathered} 1=\frac{60\text{ min}}{1\text{ h}}, \\ 1=\frac{1\text{ mi}}{1.61\text{ km}}. \end{gathered}

1) To convert the speed from km/min to mi/h, we rewrite the expression using the first ratio:


S=1.73*(km)/(m\imaginaryI n)*1=1.73*\frac{\text{km}}{\text{m}\mathrm{i}\text{n}}*\frac{60\text{ min}}{1h}=1.73*60*(km)/(h).

2) Now, we use the second ratio:


S=1.73*60*(km)/(h)*1=1.73*60*(km)/(h)*\frac{1\text{ mi}}{1.61km}=(1.73*60)/(1.61)*(mi)/(h).

3) Finally, computing the product and quotient, we get:


S\cong64.5(mi)/(h).Answer

64.5 mi/h
