At greater depths, a diver uses the air in the tank more quickly. Assume that the
amount of time the air will last is inversely proportional to the pressure at the
depth of the dive.
• Suppose a tank has enough air to last 60 min at the surface. How long will it
last at a depth of 99 ft? (The pressure is 4 atm, or 4 times as great.)
• Make a table showing how long the air will last at 0 ft, 20 ft, 33 ft, 40 ft, 50 ft,
66 ft and 99 ft.

I have already completed most of this i found 0-50ft but i need help finding the air at 66 and 99 ft
