Puzzle #7: Pass the desert

In desert, there are same types of cars available. The car runs on petrol. But each car can only carry enough petrol to cross only half of the desert.

There is no petrol station in the desert. And car can’t carry extra petrol.

You need to take an important person across the desert. You can use as many cars as you want.
