How can I detect if a timer has hit 1 minute?

I’m making a game where if you beat a tower or obstacle, meanwhile you’re doing it, there’s a timer, it will then display it in the chat that you beat it in Minutes,Seconds,MSeconds (0.00.00), however if it is under 1 minute, it will not show in chat. How can I achieve this?

			Minutes = math.floor(math.floor(workspace.DistributedGameTime-StartTime)/(60*1))
			Seconds = math.floor(math.floor(workspace.DistributedGameTime-StartTime)/(1))%(60)
			Mseconds = math.floor((workspace.DistributedGameTime-StartTime)*(100))%(100)
			script.Parent["Timer"].Digits.Text = string.format('%s:%02i.%02i',Minutes,Seconds,Mseconds)
