Starting with \(\frac{2}{3} %speech% ,two thirds,\) of a tank of fuel, I set out to drive the 550km from Scone to Canberra.

At Morisset, 165km from Scone, I have \(\frac{1}{2} %speech% ,half,\) of a tank remaining.

If I continue with the same fuel consumption per kilometre and without refuelling, what happens?
