4 kilometers.

Step-by-step explanation:

You need to analize the information provided in the exercise.

You know that:

When Allison reached the giant oak tree she would have completed 80% of the hike.When she reached the giant oak tree she had walked 16 kilometers.

Knowing this you can find the total kilometers of the hike (which is the 100% of the hike) with the following expression:

$\frac{16}{80}=\frac{total}{100}\\\\total=(100)(\frac{16}{80})\\\\total=20\ km$

Let be "x" the amount of kilometers Allison has left in the hike. This can be found with the following subtraction:

$x=20\ km-16\ km\\\\x=4\ km$
