Answer:
Aubrey ran 3 1/3 miles further than what she walked.
Step-by-step explanation:
This would be your basic subtraction problem. So, 13 1/6 - 9 5/6.
Since you can't subtract 5/6 from 1/6, let's borrow from 13. Now, instead of 13, it would be 12. Adding the whole (1) or 6/6 to the 1/6, you'll get 7/6. Now you can subtract. 7/6 - 5/6 = 2/6. Moving on, 12 - 9 = 3. 
Therefore, your answer is 3 2/6. In simplified terms, it would be 3 1/3.
