After two fast and slow trains drive from A and B at the same time for 3 hours, the express train is still 1/3 of the way away from B, and the slow train is still 150 kilometers away from A. It is known that the fast train travels 10 kilometers more per hour than the slow train. How many miles is the distance between A and B?
快慢两车同时从甲、乙两地开出3小时后，快车距乙地还有全程的(1/3)，慢车距甲地还有150千米．已知快车每小时比慢车多行10千米．问甲、乙两地的路程是多少千米？
