A construction site needs sand. If you use the same car to transport 320 cars a day, it will take 25 days to transport it. How many cars do you need to transport 5 days in advance Use the equation to solve it

We need to transport x every day
320x25=(25-5)x
20x=8000
x=400

A pile of soil, if it takes 30 days to transport 360 vehicles a day, now it needs to complete the task five days in advance, how many vehicles a day?

Suppose x cars are transported every day, (30-5) x = 360 × 30, the solution is x = 432

To transport a pile of soil, if 360 trucks are transported every day, it will take 20 days to complete; if the task is completed two days in advance, how many trucks will be transported every day? (set up an equation to solve this problem)

Solve the problem of x-car every day
（20-2）x=20×360
18x=7200
x=400
