A car driving from place A to place B, if the speed of the car is increased by 25%, then it can arrive 1 hour earlier than the original time; if the speed is increased (1/3) after driving 80 kilometers at the original speed, Arrive at B 10 minutes early. How many kilometers are there between A and B?
一辆从甲地开往乙地，如果把车速提高25%，那么可以比原定时间提前1小时到达；如果以原速行驶80千米后，再将速度提高(1/3)，那么可以提前10分钟到达乙地．甲、乙两地相距多少千米？
