Question

If Kioko can run 6 miles in 36 minutes, how far can he run in 84 minutes at this same rate?

Answer 1

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!
