Kioko can run 14 miles in 84 minutes.

Here's how I did it:

#### Explanation:

To solve this, we set up a proportion:
$\frac{6}{36} = \frac{x}{84}$
Let $x$ be the distance Kioko can run in $84$ minutes.

Now, we use this method called cross multiplication:

As you can see from this image, we multiply $6$ with $84$ and $36$ with $x$:

$6 \cdot 84 = 36 x$

$504 = 36 x$

Now we divide both sides by $36$:
$x = 14$

Kioko can run 14 miles in 84 minutes.

Hope this helps!
