Cars A, B, and C have the same planned speed, and they are all planning to go from A to B. In fact, Car A travels 20 kilometers less than the planned speed per hour, so that it takes 20 minutes longer to reach B than planned; Driving 20 kilometers per hour faster than the planned speed, this saves 20% of the time when arriving at point B; and car C arrives at point B 10 minutes earlier, so how many kilometers does car C actually travel per hour?
甲、乙、丙3辆车原计划速度相同，都准备从A到B，实际上，甲车每小时比计划速度少行20千米，这样到B地时比计划用时多20分；乙车每小时比计划速度多行20千米，这样到B地时比计划用时节约20%；而丙车提前10分到达B地，那么丙车实际每小时行了多少千米？
