From the Physics Section of the PADI Dive Theory Exam:
If it takes a diver 90 minutes to breathe all the air from a scuba tank at the surface, approximately how long will the air in that tank last at 30m/99ft?
I will post a daily question from my exams to help newer divers and to encourage more experienced divers to interact gracefully and helpfully with the newer divers.
Reminder - this is a post in the Basic Forum and it is a green zone. Please be nice and on topic.
Thank you for your patience while we try to give people something to discuss other than Covid-19 and/or Politics. I will post the answer covered by the spoiler tag later today.
