Hi All,
I'm in the process of my OW training and came across a question I don't understand the answer to. I was hoping someone here could shed some light on what I did wrong:
Question:
Imagine you have done a dive and you have stayed on the surface for a while. After this surface interval your pressure group on the Recreational Dive Planner is F. What is the maximum amount of bottom time you can spend doing a repetitive (second) dive to 17 metres/56 feet?Correct Answer(s)

. 36 minutes
Your Answer(s):A. 19 minutes
I answered 19 minutes, the correct answer was 36 minutes. why?
Thanks
Brian
