How can I add a speed factor to the scaling/position change ?

Unity Engine
1 
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ScaleOneSide : MonoBehaviour
{
    public float speed = 1;

    float mfX;
    float mfY;
    // Use this for initialization
    void Start()
    {
        mfX = transform.position.x - transform.localScale.x / 2.0f;
        mfY = transform.position.y - transform.localScale.y / 2.0f;
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButton(0))
        {
            Vector3 v3Scale = transform.localScale;
            transform.localScale = new Vector3(v3Scale.x + 0.1f, v3Scale.y, v3Scale.z);
            transform.position = new Vector3(mfX + transform.localScale.x / 2.0f, mfY + transform.localScale.y / 2.0f, 0);
        }
    }
}

When I’m pressing on the mouse left button it keep scaling it only to the right side.
But the scaling speed is at constant speed. How can I use the speed variable to change the scaling speed ?

The reason i’m not using startcoroutine is that I want to use GetMouseButton(0) pressing and not one click.
So I’m using Update for that.

What I want is when I will press the mouse left button non stop it will scale the object to one side only at a certain speed.

Update will vary in speed depending on how fast the PC is so you need to factor in Time.deltaTime.

For example, instead of doing:

v3Scale.x + 0.1f

Change it to:

v3Scale.x + ( Time.deltaTime * speed )
