On a highway, there are checkpoints D, A, C, and B arranged in sequence. A motorcyclist and a cyclist started simultaneously from A and B heading towards C and D, respectively. After meeting at point E, they exchanged vehicles and each continued to their destinations. As a result, the first person spent 6 hours traveling from A to C, and the second person spent 12 hours traveling from B to D. Determine the distance of path AB, given that the speed of anyone riding a motorcycle is 60 km/h, and the speed on a bicycle is 25 km/h. Additionally, the average speed of the first person on the path AC equals the average speed of the second person on the path BD.
