Step-by-step explanation:
The distance between A and C can be anywhere between 7 km and 21 km. If A, B, and C are in a straight line with B between A and C, then the distance is 21 km. If A, B, and C are in a straight line with A between B and C, then the distance is 7 km. If A, B, and C are not in a straight line then the distance can be any value between 7 km and 21 km.
