Question

If Sarah walked 5 kilometers this weekend, about how miles did she walk?A: 0.32B: 3.11C: 1.61D: 8.05

Answer 1

We know that 1 mile is equal to 1.61 kilometers.

You have to determine how many miles Sarah walked if she walked 5 kilometers. You can use cross multiplication to convert the units:

1.61km =1mile

5km=xmiles

`\begin{gathered} (1)/(1.61)=(x)/(5) \\ ((1)/(1.61))\cdot5=x \\ x=3.105\cong3.11 \end{gathered}`

She walked 3.11 miles
