The problem solving question said Bobby’s car uses 9 litres of fuel per 100 km. And how many litres are required to travel from Kogan to Tingura?

The distance Kogan to Tingura is 400 km and you need to find out how many litres you need if you travel 400 km. I got 36 litres.

You can just do 100 km x 4 = 400 km and 9 litres x 4= 36 litres so thats how I completed the problem solving question.
