Two vehicles, A and B, start from AB at the same time and go towards each other along the same route. After meeting, they continue to drive in the original direction. When the distance between the two vehicles is 118 kilometers, the distance between A and B is 40% of the total distance, and B has already traveled. Pass through the midpoint of the two places AB and be 30 kilometers away from the midpoint. How many kilometers is the distance between AB and AB?
甲乙两车分别从AB两地同时出发沿同一路线相向而行，相遇后继续按原定方向行驶，当两车相距118千米时，甲车与B地相距全程的40%，乙车已行过AB两地的中点并与中点相距30千米．求AB两地间的路程是多少千米？
