Question

If Karla walks 2 miles in 47 minutes, then how far will Karla walk in 77 minutes?Write answer as a integer or a reduced fraction.

Answer 1

In order to find how far Karla will go in 77 minutes, we can use the following rule of three:

$\begin{gathered} \text{distance}\to\text{time} \\ 2\text{ miles}\to47\text{ minutes} \\ x\text{ miles}\to77\text{ minutes} \\ \\ \frac{2}{x}=\frac{47}{77} \end{gathered}$

Then, solving for x, we have:

$\begin{gathered} x=\frac{77\cdot2}{47} \\ x=\frac{154}{47} \end{gathered}$

So the distance walked in 77 minutes is 154/47 miles.
