A travels from A to B in 6 hours, and B travels from B to A in 4 hours. Now A starts from A first, and B starts from B 2 hours later, and meets at the midpoint of 46.5 kilometers from AB. How many kilometers is the distance between AB and AB?
甲从A地到B地，要行6小时，乙从B地到A地，要行4小时．现在甲从A地先出发，2小时后乙才从B地出发，在距离AB两地的中点46.5千米处相遇，求AB两地的距离是多少千米？
