Endless Runner, instantiate map

Hi guys, i am pretty new to Unity , and i have a question to ask . So basically i'm making a simple endless runner (only map and obstacles move) , and map itself is a prefab , so i created trigger on a prefab, and when player hits it a new prefab map instantiates . Also i have a button "gas pedal", when you press it map starts move faster . It would be easy to locate position of where to instantiate next , if it weren't for speed, because it constantly changes. Here is my code for map instantiation:

  void OnTriggerEnter(Collider other)
     {
         if (moving.GetComponent<MoveMap>().speed != 0 )
         {
                 if (other.tag == "Player")
 
             Instantiated = Instantiate(swapped, new Vector3(distance, 0, 0), Quaternion.identity) as GameObject;
            
             
             if (Instantiated != null)
             {
                 distance = Instantiated.transform.position.x ;
                 if (Instantiated.GetComponent<TimerMap>() == null)
                     Instantiated.AddComponent<TimerMap>();
 
                 Instantiated.name = "BasicMap(Clone)";
             }
         }

Any type of help would be appreciated!
