In the light wind, a sailboat travels from A to B in 3 hours. Today, the sailboat departs from A in the breeze as usual and traveled (1/3) of the whole journey; (2/5) traveled 8 kilometers; then the wind direction became tailwind again, and the wind increased. At this time, the sailboat is traveling at twice the original speed, and arrives at point B 36 minutes later than usual. How many kilometers is the distance between point A and point B?
在微风中，一艘帆船由甲地经3小时到达乙地，今天这艘帆船照例在微风中从甲地出发，行驶了全程的(1/3)；由于风向骤变，船继而以原速度的(2/5)行驶8千米；接着风向又变得顺风，而且风力加大．这时帆船以最初速度的2倍行驶，到达乙地时比往常迟了36分钟，求甲、乙两地相距多少千米？
