Two passenger and freight vehicles are traveling towards each other from A and B at the same time, the passenger vehicle travels 30 km per hour, and the truck travels 36 km per hour. When the bus travels (3/8) of the distance between A and B, the truck is still 6 km away from the midpoint of the two places. How many kilometers are there between A and B?
客货两车分别从甲乙两地同时相向而行，客车每小时行驶30km，货车每小时行驶36km．当客车行驶了甲乙两地距离的(3/8)时，货车离两地的中点还有6km，甲乙两地相距多少千米？
