time compared to length

Is there any way to do moving from one place to another but in the same speed ? let’s say I want to move an object 150 units a second, how do I do that ?

here the actor is moving in its forward 150u/sec

and here the actor is moving from point1 to point2 at the same speed too

It’s not good in my case …
I’m trying to move an actor with a skeletal mesh with an animation while it’s moving.
I tried lots of things, but with your technique, I need to hold the mouse button (the one that executes the nodes) then just pressing it.
Can you help me maybe through skype to understand it better ?
