15 miles.

Explanation:

Displacement is the position you are in now relative to the position you were in when you started. If you had stopped at the dry cleaner's, your displacement would be 12 miles. However, you traveled back to your house and then 15 miles West of that, meaning you are now 15 miles away from your starting position.
