I am new to AS and a little confused about the relation between position and time in AS.  
If we have this code :  
[AS]  
onClipEvent(enterFrame) {  
speed = 1;  
this.\_x += speed;  
}  
[/AS]

and a framrate 16 fps, how can we calculate the time it takes to move the MC from position A to position B ?  
I mean how can vi control the speed here as a function of time (say as a function av fps) ?

Thanks for helping me with this.
