Question

Ms. Duane jogged 4.8 kilometers OR 15,840 feet. Which unit of measurement is larger? How do you know?

Answer 1

Let's convert everyone of them into meters:

$\begin{gathered} 4.8\operatorname{km}\times\frac{1000m}{1\operatorname{km}}=4800m \\ 15.840ft\times\frac{1m}{3.281ft}=4.828m \end{gathered}$

Since:

$4800>4.828$

4.8 kilometers is larger than 15.840 feet
