Josie’s car has a full tank of gas, 50 litres. She knows that if she travels at a fairly constant speed, her car uses about 1 litre of fuel for every 6 kilometres of driving. Make a table of values to represent the volume of fuel in Josie’s car after she has driven 30 km, 60km, 90 km, and 120 km.
Draw a graph of the data.
