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} \\ \\ (2)/(x)=(47)/(77) \end{gathered}`

Then, solving for x, we have:

`\begin{gathered} x=(77\cdot2)/(47) \\ x=(154)/(47) \end{gathered}`

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