How can I make it faster, because when I increase the speed, it is moving the same as before.

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

public class objectFly : MonoBehaviour
{
private float speed = 5f;
public Vector2 target;

// Start is called before the first frame update
void Start()
{
   target = new Vector2(transform.position[0] - 30, transform.position[1]);
}

// Update is called once per frame
void Update()
{

    transform.position = Vector2.MoveTowards(transform.position, target, speed * Time.deltaTime);
   
}

}
