How do you make the camera scroll faster over time

I’m trying to get my camera to move faster over time.
The script that i’m using at the moment is this.

using UnityEngine;
using System.Collections;

public class cameramovement : MonoBehaviour {
    public Vector3 Scroll = new Vector3 (0,2);

    // Use this for initialization
    void Start () {
    
    }
    
    // Update is called once per frame
    void Update () {
        transform.Translate (Vector3.up * Time.deltaTime);
    
    }
}
using UnityEngine;
using System.Collections;

public class cameramovement : MonoBehaviour {
    
    // Use this for initialization
    void Start () {
    
    }
    
    // Update is called once per frame
    void Update () {
        transform.Translate (Vector3.up * Time.deltaTime);
    
    }
}

Here is some code that linearly increases the camera speed over time. Attach to the camera or change the current code with it. Change the Speed Start and Increase Per Second values from the camera object.

public class CameraMovement : MonoBehaviour
{
	public float speedStart;
	public float increasePerSecond;
	private float secondsElapsed = 0;

	// Update is called once per frame
	void Update ()
	{
			transform.Translate (Vector3.up * Time.deltaTime * (increasePerSecond * secondsElapsed + speedStart));
			secondsElapsed += Time.deltaTime;
	}
}
