Math Test, Question # 1

A car uses fuel at a rate of 10.2 L/ 100 km while travelling at 90 km/h. At this rate of fuel consumption, how many litres of fuel would the car use if it travels 480 km? Express your answer to the nearest tenth of a litre.

This is how I solved this question:

My simple sentence answer:
