In this script, if you equip the tool your WalkSpeed boost from 16 to 30, I made it so after 15 seconds of the tool being equipped your WalkSpeed automatically goes back to 16. I also made it so if you unequipped the tool yourself your WalkSpeed goes back to 16. But it wouldn't make sense for your WalkSpeed to go back to 16 after 15 seconds and have the tool still equipped in your hand. How would I make it so after 15 seconds not only does your WalkSpeed go back to 16, but your tool automatically unequips without the user unequipping it themselves?

Script:

local tool = script.Parent
local plr = game:GetService("Players").LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()

tool.Equipped:Connect(function()
  char.Humanoid.WalkSpeed = 30
wait(15)
char.Humanoid.WalkSpeed = 16
end)

tool.Unequipped:Connect(function()
	char.Humanoid.WalkSpeed = 16
end)
