Hello all,

I am a transcriber. Let's say, I start transcribing an audio at 11:30 PM and
the audio is 60 minutes long. I have to transcribe a minute of the audio (one
minute of speaking in the audio) in 3 actual minutes. So 60 minutes should
take me three hours, which means my deadline is 2:30 AM. I should have
finished my job by 2:30 AM. Can someone help me out in generating a formula
which will calculate the deadline time? Thanks
