Min and Max value?

I've been trying to create a min and max value within a min and max value but it doesn't seem to be working for me the way i would like and I'm kinda stuck with ideas on how to achieve it.

So i have a speed of my game object and when it reaches a speed of 7 the ‘ cookedAmount ‘ will = the min2 value of 0 and when the current speed reaches 10 the ‘ cookedAmount ‘ will then = the max2 value of 3. currentSpeed = 8.5, cookedAmount = 2. currentSpeed = 9.5, cookedAmount = 2.25 so on...

I’ve tried Mathf.Lerp and Mathf.Clamp and they don’t seem to work properly.

 public bool overCooked;
 public float cookedAmount;
 public float min2 = 0;
 public float max2 = 3;
 
 
     (currentSpeed > 7 && currentSpeed < 10) 
         {
             overCooked = true;  
             cookedAmount = Mathf.Lerp (min2, max2, currentSpeed / 11.5f);
         } 

attempt two,

     public bool overCooked;
     public float cookedAmount;
     public float min2 = 0;
     public float max2 = 3;
 
     
         (currentSpeed > 7 && currentSpeed < 10) 
             {
                 overCooked = true;  
                 cookedAmount =  Mathf.Clamp  (currentSpeed * 0.25, min2, max2);
             }
