How do I fix this script so that it displays a number in minutes?

I have this script that makes a round that repeatedly teleports a player back and forth between the lobby and game area. Its been working so far but the roundLength is being displayed in seconds while I would want it to display in minutes. I have tried to turn it into increments of 60 so far but I haven't fixed it.

local roundLength = 1000
local intermissionLength = 60
local InRound = game.ReplicatedStorage.InRound
local Status = game.ReplicatedStorage.Status

local LobbySpawn = game.Workspace.LobbySpawn
local GameAreaSpawn = game.Workspace.GameAreaSpawn


InRound.Changed:Connect(function()
    wait (1)
    if InRound.Value == true then
        for _, player in pairs(game.Players:GetChildren()) do
            local char = player.Character
            char.HumanoidRootPart.CFrame = GameAreaSpawn.CFrame
        end
    else
        for _, player in pairs(game.Players:GetChildren()) do
            local char = player.Character
            char.HumanoidRootPart.CFrame = LobbySpawn.CFrame
        end
    end
end)



local function roundTimer()
    while wait() do
        for i = intermissionLength, 0, -1 do
            InRound.Value = false
            wait(1)
            Status.Value = "Intermission: ".. i .." seconds left!"
        end
        for i = roundLength, 0, -1 do
            InRound.Value = true
            wait(1)
            Status.Value = " ".. i .." seconds until Alpha Warhead detonation!"     
        end
    end
end

spawn(roundTime
