Cars A and B start from places a and b at the same time and drive towards each other. When car A travels (1/4) of the whole journey, B is still 60 kilometers away from the midpoint. And their speed ratio is 2:3, then how many kilometers are the distance between a and b?
甲、乙两车同时从a、b两地出发相向而行，当甲车行了全程的(1/4)时，乙距离中点还有60千米．并且它们的速度比是2：3，则a、b两地的路程是多少千米？
