The number line shows the distance, in meters, of two divers, A and B, from a shipwreck located at point X: a horizontal number line extends from negative 3 to positive 3. The point labeled as A is at negative 2.5, the point 0 is labeled as X, and the point labeled B is at 1.5

Part A: Write an expression using subtraction to find the distance between the two divers. (5 points)

Part B: Show your work and solve for the distance using additive inverses. (5 points)
