Here's an example:
frames 19.20, distance 1.08, duration 0.8, my calculation 1.08÷0.8=1.35
Calculation using the formula ((10÷19.20)×3)×1.08 =1.6875

But, in any case, your formula seems to be better than ours with FrozenSoul, as it is shorter and simpler.

Well, in principle, it sounds logical. We divide the number of frames by 24 to get the animation's duration in seconds. Because 24 frames per second is the standard frame rate. Next, we divide the distance by the time to get the speed. It's funny how we didn't figure this out before. Someone needs to thoroughly check this formula. In theory, it should work normally, but it's always better to check. It seems that it is better than the one that FrozenSoul and I wrote earlier.
