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)
Part A: The expression using subtraction to find the distance between the two divers is: B - A.
Part B:
B - A = (1.5) - (-2.5)
= 1.5 + 2.5
= 4
Therefore, the distance between the two divers is 4 meters.
