If AB = 4 and BC = 7, and A, B, C are collinear with B between A and C, what is AC?

Explanation:
When a point lies between two others on the same line, the distance from the outer points equals the sum of the distances from the middle point to each outer point. Here, the distance from A to B is 4 and from B to C is 7, and B is between A and C, so AC = AB + BC = 4 + 7 = 11. Therefore, the distance from A to C is 11.
