Car A and car B are traveling towards each other from A and B at the same time. Due to the slippery road in rainy weather, car A travels 15 km less than the original plan, and car B travels 7 km less than the original plan. After 5 hours, the two cars meet. The distance between B and B is 440km. Ask how many kilometers per hour the two cars of A and B planned to travel?
甲车和乙车同时从A、B两地相向而行，因雨天路滑，甲车比原计划少行15km，乙车比原计划少行7km，5小时后两车相遇，已知甲、乙两地相距440km，问甲乙两车原计划每时行多少千米？
