local train and an express train depart from Station A and Station B respectively. The ratio of the speed of the express train to the local train is 5:4. The local train first leaves Station A for 27 kilometers, and the express train departs from Station B. When they meet, the distance between the express train and station B is 32 kilometers longer than the distance between the local train and station A. How many kilometers are the distance between stations A and B?
一列慢车和一列快车分别从A、B两站相对开出，快车和慢车速度的比是5：4，慢车先从A站开出27千米，快车才从B站开出．相遇时快车和B站的距离比慢车和A站的距离多32千米，A、B两站相距多少千米？
