Answer:

  7/33 mile

Step-by-step explanation:

If we designate the locations of Ben, Shaneeka, and Phil by point B, S, and P, respectively, the segment addition theorem tells us ...

  PS + SB = PB

Filling in the given distances, we have ...

  PS + 1/3 = 6/11

Subtracting 1/3, we can find the distance between Shaneeka and Phil:

  PS = 6/11 - 1/3 = (18 -11)/(33) = 7/33 . . . . miles

Shaneeka lives 7/33 mile from Phil.

_____

Addition and subtraction of fractions can be done using the formula ...

  a/b +c/d = (ad +bc)/(bd)

Of course, any of the numbers can be negative.
