Earth moves with somewhere between 230-500km/s, long term average should be 370 km/s

The solar system and earth formed 4.6 billion years ago.

That means the solar system travelled 3.45-7.67 million light-years (5.67 for the average speed) since then.
That plural form (millions of light years) is borderline, but actually not incorrect.
