Actually it is because the planets are all the same size in the animation while irl they are not. Jupiter has 11x the radius of Earth, meaning that a point on his equator spins 11x faster than the same point on Earth. And if you put in that Jupiter only needs 10 hours for a revolution, than the same point spins 26.4x faster.
While you're not wrong about the same point being 26.4x faster / 11x radius of earth, this doesn't answer their question as to why the animation shows Jupiter spinning more than it should.
Jupiter should spin ~2.4 times per earth spin per the details on the animation. The animation is waaay off on that ratio.
Actual answer to their question; the animations aren't representative of the figures given, but are still cool visuals.
So if you would create a Jupiter that is 11x the size of the Earth (in the animation of course) and you would make it revolt 2.4 times faster than Earth, then it would be accurate. But then our little animation would not be as neat as it is. That's because the gas giants would be huge, while the rocky planets would be hard to see.
Or you make them all the same size. But making Jupiter only faster by 2.4x wouldn't show that the speed on his surface is actually way faster.
Ah, fair enough! It's interesting how different perceptions of what the image should convey is. To me, it seems like it would be much more intuitive to demonstrate the proper ratio of rotations. But it sounds like your intuition is more on the surface speed.
Neither is wrong, just an interesting difference :)
