Speed up a Tween (cs4 AS3)

[mdermez]

I have an animated fish crossing the screen. I made that using the animated fish (movieclip1) following a path on a guide layer. All these are into another movieclip (2).
I want in mouse hover condition to accelerate the tween. In other words I want the user to point the fish with the mouse (mouse hover) and then the fish tries to escape (tween acceleration). How can I accelerate the tween?

Keep in mind that in fish movieclip(1) I have more than one Tweens. So the code must be for selected tween (named by frame label).

Another thing is that acceleration mustn't be directly from 0 to 1. There must be an ease on the start and on the end of acceleration so it can be more realistic.

I am not related on programming so I would like a complete answer (not just directions)

My thinking of the code was:

(if it's needed I'll have to import transitions.ease and tween)

Function for mouse hover condition
--> inside that function I have to define (I think) another function about acceleration of the tween

Then I have to add eventListener for the object.

So my main question for the code is focused on tween acceleration
