Pain in the ass

I must say "Pain is the ass" is a very unhelpful title. Something like "Moving an object a certain distance over time" would be better.

I think this might get you close to where you are wanting to go. It's a rough sketch (not tested). Good luck!

     // example: slide(Vector3(-10, 0, 0), 1)
     function slide(howMuchToSlide : Vector3, howLongWillItTake : float) {
         var timeSpent : float = 0.0;

         // keep moving until time is up
         while(timeSpend < howLongWillItTake) {
             // update our time counter 
             timeSpent += Time.deltaTime;
 
             // breaks total movement into however many steps needed to cover that 
             // distance within the time limit specified
             var step = howMuchToSlide / howLongWillItTake;
 
             // then move the object by that total step movement
             transform.Translate(step * Time.deltaTime);
 
             // make sure to wait for that long to make sure it takes effect
             yield WaitForSeconds(step * Time.deltaTime);
         }
     }
