How to lerp over time help?

Hi everyone. This is probably a simple question, but I have this Lerp script -
if (moving == true){
transform.position.x = Mathf.Lerp(-8.5, 2.3, 1);}
}
How can I make the lerp move from one point to another over a time period of 2 seconds instead of instantly?

Change the 1 in the Lerp for the time. Note that it has to be between 0 and 1.

float currentTime = 0f;
float timeToMove = 2f;

void Update() {

    if (moving == true)
    {
        if (currentTime <= timeToMove)
        {
            currentTime += Time.deltaTime;
            transform.position.x = Mathf.Lerp(-8.5f, 2.3f, currentTime / timeToMove);
        }
        else
        {
            transform.position.x = 2.3f;
            currentTime = 0f;
            moving = false;
        }
    }

}
