I need some help in trying to change the position of an gameobject and its speed. I know to translate the gameObject but I don't know how to increase the speed of how it translates. I'm using the unity game engine by the way. 

```
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class lightning : MonoBehaviour
{
    //This is lightning
    private GameObject name;

    // Start is called before the first frame update
    void Start()
    {
       name=GameObject.Find("car");
    }

    // Update is called once per frame
    void Update()
    {
     if (Input.Keydone("r")
       door.transform.Translate(-Vector3.right * Time.deltaTime);
    }
}

```
