Calculate time to destination taking account current speed, also how to determine distance between two objects?

Hi, I created this script that calculates the Distance between two objects (That i called Object1 and Object2) using the Vector3.Distance function. To know the Time to reach the object (supposing that only Object1 will move) simply use the formula: Time = Distance / Speed.

     public GameObject Object1;
     public GameObject Object2;
 
     public float Distance;
     public float TimeBetweenObjects;
     public float Speed;

     void Update()
     {
         Distance = Vector3.Distance(Object1.transform.position, Object2.transform.position);
         TimeBetweenObjects = Distance / Speed;
 
         Object1.transform.position = Vector3.MoveTowards(Object1.transform.position, Object2.transform.position, Speed * Time.deltaTime);
     }
