Elementary school students in the third grade made a math paper by themselves

Zhang Dong took a total of 6 kilometers and Li Hua 12 kilometers. Xiaowei 18 kilometers, 36 yuan, then 2 kilometers of kilometers. So Zhang Dong paid a total of 12 yuan when he got off the bus, but Li Hua and Xiaowei also took it together, so 12 3 = 4 yuan (everyone has to pay 4 yuan), and then traveled 6 kilometers, then 6 * 2 = 12 yuan, there are only two people left, so divide by 2 (12 2 = 6 yuan, Xiaowei and Li Hua each pay 6 yuan), and the sum just now is 6 + 4 = 10 yuan, and finally Xiao Wei is left, he took 6 kilometers alone 2 * 6 = 12 yuan, plus the previous 12 + 4 + 6 = 22 yuan.

It can be understood like this:

The total distance is 18 kilometers, 36 yuan, 2 yuan per kilometer. The first 6 kilometers is 12 yuan, and 3 people share it equally, which should be 4 yuan per person; the second 6 kilometers is 12 yuan, and the average share of 2 people is 6 yuan; The third 6 kilometers, 12 yuan, 1 person alone.

Therefore, Zhang Dong is 4 yuan, Li Hua is 4 + 6 = 10 yuan, and Xiaowei is 4 + 6 + 12 = 22 yuan.

Zhang Dong traveled 6 kilometers by car, Li Hua traveled 12 kilometers by car, Xiaowei traveled 18 kilometers by car, and the three of them traveled 36 kilometers, and they should pay according to the number of kilometers each person cared. 36 (yuan) 36 (km) = 1 (yuan km), Zhang Dong payable 1 6 = 6 yuan, Li Hua: 1 12 = 12 yuan, Xiaowei:

1 18 = 18 yuan. It's over.

Zhang Dong took 6 kilometers, Li Hua took 12 kilometers, Xiaowei took 18 kilometers, and the three of them took a total of 6 + 12 + 18 = 36 kilometers.

Xiaowei gave a total of 36 yuan, that is, 36 36 = 1 yuan per kilometer, so Zhang Dong wanted to give 6 * 1 = 6 yuan, Li Hua wanted to give 12 * 1 = 12 yuan, and Xiao Wei wanted to give 18 * 1 = 18 yuan.

A total of 36 yuan was spent, and the three of them traveled 6 kilometers from Zhangdong, 12 kilometers from Li Hua, and 18 kilometers from Xiaowei, with a ratio of 1:2:, so Zhang Dong 6 yuan, Li Hua 12 yuan, and Xiaowei 18 yuan.

36 (1+2+3)=6 yuan.

6 times 2 = 12 yuan.

6 times 3 = $18.

Zhang Dong 6 yuan, Li Hua 12 yuan, Xiaowei 18 yuan.

Proportionally, 18km is 1 3, 2 3, 1So it adds up to a total of 2 and then Zhang Dong: 18 1 3 = 6 Li Hua 18 2 3 = 12 Xiaowei 18 1 = 18

Zhang Dong 6 Yuan 36*[6 (6+6+6+6+6+6)].

Li Hua 12 yuan 36*[(6+6) (6+6+6+6+6+6)]

Xiaowei 18 yuan 36*[(6+6+6) (6+6+6+6+6+6)]

Zhang Dong 6 yuan.

Li Hua 12 yuan.

Xiaowei 18 yuan.

Because their travel ratio is also 1:2:3

The second to get off is 2x plus 2 for the first to get off
