The pressure on a diver can be
calculated using the formula P = 15+1/2D, where P is the
pressure in pounds per square inch and D is the depth in
feet. Use this formula for Exercises 44 and 45.
44. Find the depth of a diver when the pressure on the diver
is 45 lb/in².
45. Find the depth of a diver when the pressure on the diver
is 55 lb/in².
