Suppose that Brian lives at B. Suppose Simran lives at S.  All we are told about
Aram is that he lives 5 miles from Brian.  So Aram could live anywhere on the
circle.  

If Aram lives at A<sub>1</sub>, then Aram's house is 15.5 miles from Simran's house.
That's the maximum distance.

If Aram lives at A<sub>2</sub>, then Aram's house is 3.5 miles from Simran's house.
That's the minimum distance.

If Aram lives at A<sub>3</sub> or A<sub>3</sub>, then Aram's house is 9.9 miles from Simran's house, 
(the green lines show this distance.)  

That's why the distance cannot be determined from the information given
