An easy way of doing it would be to set the .Container-4 to Flex, with justify Space-Between. Then move the .Nav-Menu above the .Div-Block-4 in the navigator. Set .Nav-Menu Flex Child Order to First, and .Div-Block-4 Flex Child Order to Last:
The other common approach is to leave everything inline simply float the menu left, and float the image right. Up to you. I personally like using flex when the content lives in a single row.
