How do I Animation speed based on real speed

Hi i want to create a rolling ball game , but i dont want to use physics and such. I want simple platform behaviour , and the ball will have rolling animation on it. And when you go faster the animation will adapt accordingly. How would i do this please?

Set animation speed of your sprite proportionally to your speed value. (probably in the event that determines/changes your speed)

You find it under sprite -> animations -> set speed.
