The car travels from A to B at a speed 6 kilometers slower than the predetermined speed, and the arrival time is longer than the predetermined time (1/8). If the arrival time is to be 1 hour earlier than scheduled, the speed must be increased (1/3) than scheduled, find the distance between A and B.
汽车以比预定的速度慢6千米从A到B地，到达时间比预定时间多(1/8)．如果要使到达时间比预定的提早1小时，速度必须比预定的增加(1/3)，求AB间的距离．
