AI Pathfinding script with Speed Adjustment

Hello, I am new to unity and have copied a Pathfinding script from this video: https://youtu.be/atCOd4o7tG4

But the agent runs way too fast. How can I make the speed of the agent be the float speed. I appreciate any response, thanks in advance

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

public class EnemyNavMesh : MonoBehaviour {

  public float speed;
 
  [SerializeField] private Transform movePositionTransform;
 
  private NavMeshAgent navMeshAgent;
 
   private void Awake(){
      navMeshAgent = GetComponent<NavMeshAgent>();
   }
 
  private void Update (){
      navMeshAgent.destination = movePositionTransform.position;
  }
   
 

}
