Cars A and B are traveling towards each other from places A and B at the same time. Car A travels 80 kilometers per hour, and car B travels 100 kilometers per hour. After 8 hours, the two met. Xiao Ming thought that the last two cars met at a distance of 40 kilometers from the finish line, while Xiao Pang thought that they met at a distance of 20 kilometers from the midpoint. Who do you think is right? Why?
甲乙两车同时从A、B两地相向而行．甲车每小时行80千米，乙车每小时行100千米．经过8小时两人相遇，小明认为最后两车是在离终点40千米处相遇，而小胖认为他们是在离中点20千米处相遇，你认为谁对？为什么？
