How to get the speed of rotation or movement?

Hi! How can I get the speed of rotation, if I set "every tick" "angle toward position"?

And Is it possible, to get the speed of movement separately for x, and y without using any behavior? I know that there is an expression for physics behavior, like "VelocsityX, and VelocityY. But I can't understand how to get the speed, if my object moves using different formulas.
