No. Sure there is twice as much wind resistance at 30 mph than there is at 60mph - it's a square law. But MPG isn't based solely on wind resistance, another important consideration is how efficient the engine is working. I got my best tank going 75-85 on california freeways.
Inversely proportion isn't quite the right mathematical wording to describe the relationship because, again, it's a square law.
