Problema Solution
The pressure, p, on a diver varies directly with the depth, d. If the pressure is 4.8 lb/in^2 when the depth is 12ft., what is the pressure when the depth is 20ft?
Answer provided by our tutors
since the pressure varies directly with the debt can write the following proportion
4.8 : x = 12 : 20
x = (4.8 * 20) / 12
x = 8 lb/in^2 the pressure when the depth is 20ft
