A car drives from place A to place B. If the speed increases by 20%, it can arrive one hour earlier than the specified time. In fact, it travels 20 kilometers more per hour, and the result is less than the scheduled time (1/3). How many kilometers is the distance?
一辆汽车从甲地开往乙地，如果速度提高20%，可比规定时间提前一小时到达，实际上每小时多行20千米，结果比预定时间少(1/3)，甲乙两地的路程是多少千米？
