Question

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 the distance between C and D is 8, what is the distance between B and D ? (1) The distance between C and A is the same as the distance between C and B. (2) A is to the left of D on the number line.

Answer 1

insufficient information

Explanation:

If the order of the points is unknown, the distances AB and CD imply no particular distance for BD.
