Want to know how many kilometers Zhuhai drives to Xi 'an, and how much is the toll and postage? One person 1400, three people * * * Which is more cost-effective?

Baidu takes a trip from Zhuhai to Xi 'an about 177 1.5 km, and Mondeo's Zhisheng Expressway is very fuel-efficient. Let's estimate that a box of oil runs 800 km, and a box of oil is 400 yuan, which is about 0.5 yuan /km, 177 1 km. The fuel cost is about 886 yuan, which is counted as 900 yuan. After all, there are still some things that cannot be counted. Expressway is about 0.3 yuan /km, and the road and bridge fee is about 535 yuan (this estimate is a little small, it seems that around 600 should be almost the same). It is estimated that it will take two days to run on the road, plus the cost of eating three meals and staying overnight in the evening. This has to be calculated by myself. If three people count, driving seems to be cost-effective. But it's still hard.
