A truck transporting material to a factory requires 190 litres of gas for every trip to cover 1,500 km. How many litres of gas will it require to cover 1,950 km?

Answer 1

To cover 1,500 km, the truck requires 190 litres of gas.
Therefore, for 1 km, the truck requires 190/1500 = 0.1267 litres.
Therefore, for 1,950 km, the truck will require 0.1267 * 1,950 = 247.335 litres of gas. Answer: \boxed{247.335}.
