Two passenger and freight vehicles depart from A and B oppositely at the same time. The ratio of the distance traveled by passenger and freight vehicles when they meet is 5:4. After the meeting, the trucks traveled 36 kilometers more per hour than before the meeting, and the passenger cars still moved forward at the original speed. As a result, the two cars arrived at the departure station of each other at the same time. It is known that the bus has traveled for a total of 8 hours. How many kilometers is the distance between A and B?
