The distance between A and B is 375 kilometers. A car travels from A to B. After 1.5 hours, B travels from B to A. A travels 60 kilometers per hour, and B travels 54 kilometers per hour. , How many hours after car B leaves, the two cars meet? (Arithmetic first, then equation solution)
A、B两地相距375千米，甲车从A地开往B地，1.5小时后，乙车从B地开往A地，甲每小时行60千米，乙车每小时行54千米，乙车开出几小时后两车相遇？(先用算术法，再用方程解)
