Two trains, A and B, depart from the two cities at the same time in opposite directions. When train A travels 36 kilometers less than train B, the distance between the two trains is still 264 kilometers. Given that the ratio of the speeds of cars A and B is 5:6, find the distance in kilometers between the two cities.
甲、乙两列火车分别从两城同时相向开出，在甲车比乙车少走36千米时，两车还相距264千米．已知甲、乙两车速度的比为5：6，求这两城相距多少千米．
