The rate at which a scuba diver uses air in the tank depends on many factors, such as the diver's age and lung capacity. another important factor is the depth of the dive. a scuba diver continues to breathe normally while descending. every time the diver inhales, the tank delivers enough air to inflate the diver's lungs. this means that the amount of air delivered by the tank must increase with the depth to withstand the increasing pressure. at greater depths, the diver uses the air in the tank more quickly. the amount of time the air will last is inversely proportional to the pressure at the depth of the dive. 9) the amount of time (t) the air will last is inversely proportional to the pressure (p) at its depth. a) write an inverse variation that models the relationship between t and p. b) suppose a tank has enough air to last 60 minutes at the surface. the pressure is 1 atm at the surface. solve for k. c) the pressure is 4 atm at a depth of 99 ft. how long will it last at a pressure of 4 atm? 10) create a table showing how long the air will last at 0 ft, 33 ft, 66 ft, and 99 ft. construct your table to include three columns. the first column should be the depth in feet, the second the pressure in atm, the third the time in minutes.
