Money represents mileage, that is, they are charged according to their respective mileage. They take 9. 10. 12 unit mileage, that is, their respective mileage is divided by the total mileage of 3 1 and then multiplied by 12 yuan, but this seems reasonable, but the premise is that the passengers behind them don't follow the ones in front. If there is a detour, I think it is a little more balanced and reasonable, saving a lot of time and cost.
