A car drives from A to B, if the speed increases by 20%, it can arrive 1 hour and 30 minutes later than the original time; if it travels 200 kilometers at the original speed and then increases the speed by 15%, it can arrive 36 minutes earlier , How many kilometers is the distance between A and B?
一辆汽车从甲地开往乙地，如果车速提高20%，可以比原定时间提高1小时30分钟到达；如果以原速度行驶200千米后再把车速提高15%，则提前36分钟到达，甲、乙两地相距多少千米？
