The distance between A and B is 575 km. Two passenger and freight vehicles are traveling towards each other from two places at the same time, and meet each other in 5 hours. When they meet, the bus travels 25 kilometers longer than the truck, and the bus travels 60 kilometers per hour. How many kilometers per hour does the truck travel? (How many solutions can you think of?)
甲、乙两地相距575千米．客货两车同时从两地相向而行，5小时相遇．相遇时，客车比货车多行25千米，客车每小时行60千米，货车每小时行多少千米？(你能想出几种解法来？)
