This gives practice for modeling distance.

How You Can (And Should) Get More Practice!

Below is a few practice problems of various difficulty, but you will need considerably more practice than one each. For that reason you should definitely use the green “Try Another” button in the top right corner at least two or three times to complete additional versions of these questions for more practice. You should keep using that button until doing these problems feels straight forward and easy, and then come back after a week or so of doing other stuff and try again to make sure it is still just as easy for you.

Theoretically Easier Difficulty Problem

Recall, the distance between and is represented by .
Remember to be careful with negatives. It’s best to plug in the expressions in parentheses when you are writing it as to represent the distance between and .
