It is known that the speed of car A is 90 kilometers per hour, and the speed of car B is 60 kilometers per hour. Cars A and B start from places A and B at the same time and go towards each other. When passing through place C, car B arrives earlier than car A 10 minutes; the next day, A and B depart from B and A respectively and return to the original starting point at the same time. When passing through C, A’s car arrives 1.5 hours earlier than B’s. So what is the distance between A and B?
已知甲车速度为每小时90千米，乙车速度为每小时60千米，甲乙两车分别从A，B两地同时出发相向而行，在途径C地时乙车比甲车早到10分钟；第二天甲乙分别从B，A两地出发同时返回原来出发地，在途径C地时甲车比乙车早到1个半小时，那么AB距离时多少？
