The number line shows the distance, in meters, of two skydivers, A and B, from a third skydiver 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 0.5.

Part A: Write an expression using subtraction to find the distance between skydivers A and B. (5 points)

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