How do I make a fly script that gets slower the less hp you have?

so I have this little bit of code:

flyVel.Velocity = CFrame.new(workspace.Camera.CFrame.Position, Mouse.Hit.Position).LookVector * (speed / Character.Humanoid.Health)

and obviously it doesn’t work because dividing your health is going to make your fly speed slower the more health you have. but i’m not really sure how else I can do this… Does anyone have a clue how?

local HealthMultiplier = Humanoid.Health / Humanoid.MaxHealth
flyVel.Velocity = CFrame.new(workspace.Camera.CFrame.Position, Mouse.Hit.Position).LookVector * (speed * HealthMultiplier)
