Answer:

Kioko can run 14 miles in 84 minutes.

Here's how I did it:

Explanation:

To solve this, we set up a proportion:
#6/36 = 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 * 84 = 36x#

#504 = 36x#

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

Kioko can run 14 miles in 84 minutes.

Hope this helps!
