So the car makes  400km%2F50liters = 8 km per liter of the fuel.


Using 20 liters, the car will cover  8*20 = 160 kilometers.    ANSWER



     Or, you can write the proportion  400%2F50 = x%2F20



and find the unknown distance  x  from it  x = %28400%2A20%29%2F50 = 8*20 = 160 kilometers,

getting the same answer.

Solved.
