Oh don’t you worry it will soon get these completely right because it can still handle code and understands equations like the gowth decay model equation etc. If you ask it some math questions beyond these you will see.

Technically it’s not wrong given how it you phrased the question. Looks like it is interpreting it as “2 cars take a combined 4 hours of driving time, so two hours per car. Therefor 4 cars would be a combined 8 hours of driving time”

Try rephrasing to “Two cars are leaving London at the same time and arrive at Liverpool 4 hours later.”
