Two trains are traveling towards each other from AB respectively. A train travels from A to B at a speed of 65 kilometers per hour, and when B travels from B to A at a speed of 70 kilometers per hour, there is a train at the same time. A car travels from A to B along a road parallel to the railway. After a few hours, the two trains meet. After a while, the second train meets the car. If the previous period is five times that of the latter period, then the speed of the car is How many kilometers per hour.
两列火车分别从AB两地相向而行，甲车从A地以每小时65公里的速度向B地行进，乙车从B地以每小时70公里的速度向A地行时，同时有一辆汽车从A向B沿与铁路平行的公路行驶，若干小时后两列火车相遇，又过了一段时间，乙车与汽车相遇，若前一段时间是后一段时间的5倍，那么汽车的速度是每小时行多少公里．
