Answer:

13 miles

Step-by-step explanation:

43-4=39      you use the inverse operation. you subtract 4 from 4, you get 39.

                                                                                                                                   

39/3=13       then, you also do the inverse operation. you divide 39 by 3, you        

                   get 13 as your answer.
