1.Use the map shown below to find the distance between cities A and B to the nearest tenth. 2.Find (a) PQ to the nearest tenth and (b) the coordinates of the midpoint of PQ P(-2,-3), Q(1,3) (a) PQ= 3. For the graph shown on the right find (a) AB to the nearest tenth and (b) the coordinates of the midpoint of AB (a) AP= 4. In a three-dimensional coordinate system, the distance between two points (x1,y1,z1) and (x2,y2,z2) can be found with the extension of the distance formula shown below. Find the distance between T(0,5,-1) and V(2,13,3)

Which one is the correct answer, and why?
