The points A, B, C and D are on a number line, not necessarily in that order. If the distance between A and B is 18 and that between C and D is 8, what is the distance between B & D?

1) The distance C & A is the same as that between A & B
2) A is to the left of D on the number line.

B ... 18 ... A ... 10 ... D ... 8 ... C -> BD = 28
B ... 18 ... A ... 18 ... C ... 8 ... D -> BD = 44
