We have the following:

Since it is a proposition, we can calculate the liters of fuel for any number of kilometers with a proportionality rule as follows


\begin{gathered} 476\rightarrow17 \\ 1428\rightarrow x \\ x=(1428\cdot17)/(476) \\ x=(24276)/(476)=51 \end{gathered}

Therefore 51 liters of fuel are needed
