Garages that can enlarge buses (buses are usually12m) are generally about13m, and the three garages are the same size, so the first enlarged bus and the second can hold three cars (cars are generally 4.5m), and the other garage can hold a sports car and a van by exclusion method, because the length of the van is generally the length of two cars! If I explain this problem, it is that cars and sports cars are all 1, trucks are 2, and buses are 3, so there are 9 cars in total, so it is more reasonable to divide them into three garages!
