I make a camera that change position every X seconds but i need different waiting time for each position that take.

I was dealing with invokerepeating:

  InvokeRepeating("ChangePosition",getTimeforEachScene(transform.position.x), getTimeforEachScene(transform.position.x));

 public float getTimeforEachScene(float positioCam)
     {
         
         float designedtime = 0;
         if (positioCam == 0F)
         {
             designedtime = 0.3F;
         }
 
         if (positioCam == 20F) {
             designedtime = 10F;
         }
         if (positioCam == 40F)
         {
             designedtime = 0.3F;
         }
         return designedtime;
     }

but I noticed that it is not the correct way. **The camera moves in axis x + 20F every few seconds, but in this case I want each plane to take the focus of the camera, but each take a separate focus time, it is not the same time for all 3 planes.**like a movie scenes. then check it out and say it can be done with Coroutines, it would help me a lot if I any of you guys have some example that more or less suited my case. Thanks in advance guys.
