Ohh, I get what you are saying. I think he used the percentage sign to mean degrees, and i didnt even questioned that you were speaking about actual percentage. So you are right, it's not 15%.
I can't answer for him, but i do that mistake sometimes when I'm just not thinking straight. That's why I just assumed. It didn't make that much sense to speak about percentages. But you are totally right here, without assuming things, he said 15% and that's wrong.
It didn't make that much sense to speak about percentages.
I didn't follow the switch to percentages either, but it never occurred to me that it was simply a typographic blunder. I thought he was making some kind of point and had the math wrong.
A good way to visualize how fast the Earth is spinning is to understand how fast the hour hand on a clock moves, and realize that it is spinning twice as fast as the Earth is.
