The distance between A and B is 22.4 kilometers. A parade starts from point A and moves toward point B at a constant speed. When the parade leaves A at the end, A and B walk towards each other at the same time at places A and B respectively. After the tail of the team, it turns around and chases the head of the team, and repeats this way. When A catches up with the head of the team for the fifth time, he meets B at a distance of 5.6 kilometers from B; Arriving at point B, how many kilometers away is B from point A at this time?
A、B两地相距22.4千米．有一支游行队伍从A地出发，向B匀速前进．当游行队伍尾离开A时，甲、乙两人分别多A、B两地同时相向而行，乙向A步行，甲骑车先追向队头，追上之后又立即骑向队尾，到达队尾之后又掉头追队头，如此反复，当甲第5次追上队头时恰与乙相遇在距B地5.6千米处；当甲每7次追上队头时，甲恰好每一次到达B地，那么此时乙距离A地还有多少千米？
