This sounds too much like an exam question.

You remember what a half time is?
Well the 60 minute compartment has had one, the 20 minute has had three etc.
So you know what the nitrogen was on the surface, 0.79bar.
You know where it's going to at 18 meters, abs pressure times 0.79.
So the 60 minute one covered half the gap, the 20 minute one covered seven eighths etc.

Now you have the answer in nice simple bar you can tell me why you put this question in the FAQ forum.
