A car was driving from place A to place B. After driving 120 kilometers at the original speed, a breakdown occurred. After an hour of repairs, the car started again. In order to arrive on time, the driver increased the speed by 25%, and the result was 20 minutes late arrive. If you increase the speed by 20% from the time of departure, you can arrive 1 hour earlier than the original time (this does not consider the situation where the car breaks down). So how many miles is the distance between A and B?
一辆汽车从甲地开往乙地，在以原速行驶120千米后出现了故障，经过一小时的修理，汽车再次出发，为了准时到达，司机将车速提高25%，结果晚了20分钟到达．如果从出发时就将车速提高20%，可以比原定时间提前1小时到达(这里不考虑汽车出现故障的情况)．那么甲、乙两地相距多少千米．
