How to go from position A to B in x second

Question

basically my code is working fine and all is good. My only problem is that the character is changing position is splits of seconds from this line

float perc = currentLerpTime / lerpTime;
        var _CurrentPosition = gameObject.transform.position.x;
        var DesiredPosition = Mathf.Lerp (_CurrentPosition, _CurrentPosition + evadeForce, perc);
        gameObject.transform.position = new Vector2 (DesiredPosition, gameObject.transform.position.y);

the code above gets current position then lerps to new position then applies it. but it is happening too fast like the player is disappearing. instead i want it to be slower.

basically instead of going from A to B in 0.1 seconds I want it to go from A to B in 1 second.

Here is the full code:

IEnumerator _EvadeAttacks() 
{
    Physics2D.IgnoreLayerCollision(playerLayer, EnemyLayer, true);
    currentLerpTime = 0f;
    currentLerpTime += Time.deltaTime;
    if (currentLerpTime > lerpTime) {
        currentLerpTime = lerpTime;
}
    if (!evadeLeft) 
    {
        Debug.Log ("workingright");
        float perc = currentLerpTime / lerpTime;
        var _CurrentPosition = gameObject.transform.position.x;
        var DesiredPosition = Mathf.Lerp (_CurrentPosition, _CurrentPosition + evadeForce, perc);
        gameObject.transform.position = new Vector2 (DesiredPosition, gameObject.transform.position.y);
        hasEvaded = true;
    } else if (evadeLeft) 
    {
        Debug.Log ("workingleft");
        float perc = currentLerpTime / lerpTime;
        var _CurrentPosition = gameObject.transform.position.x;
        var DesiredPosition = Mathf.Lerp (_CurrentPosition, _CurrentPosition - evadeForce, perc);
        gameObject.transform.position = new Vector2 (DesiredPosition, gameObject.transform.position.y);
        hasEvaded = true;
    }
    canWalk = true;
    yield return new WaitForSeconds(SecondsToWaitForEvadeCollider);
    Physics2D.IgnoreLayerCollision(playerLayer, EnemyLayer, false);
    yield return new WaitForSeconds (SecondsToWaitForEvadeReset);
    hasEvaded = false;
}

Since you change only X i will create function for only X change. If you want to change both, just modify it.

public void MoveGameObject(GameObject go, double Y,  double currentX, double desiredX, double moveSpeed)
{
    double K = moveSpeed * 0.1; //Try different moveSpeed for effect
    double D = (desiredX - currentX) / K;
    double X = currentX;

    for(int I = 0; I < K; I++)
    {
        X += D;
        go.transform.position = new Vector2 (X, Y);
    }
}

If there is mistake (I have done it from head without testing), tell me what it is and I will correct it.
