The starting price of Xiaohong's city is three yuan (including 1 km). /kloc-boarding at 0/0: 25,/kloc-getting off at 0/0: 50, taxiing speed 36 km/h, how much do you have to pay?

36 * (1/2)-1* 3 = 51yuan

In the above answer.

1) The time should be 25 minutes, so the boarding time is changed to 10:20.

2) The starting price is not the unit price, so the unit price should be increased to 1.8 yuan/km.

According to the topic calculation:

(36/2-1) *1.8+3 = 30.6+3 = 33.6 yuan.
