As an object's depth below the surface of a body of salt water increases, so does the pressure
acting on the object due to atmospheric and water conditions. The rate at which pressure
increases is approximately 11 pounds per square inch (psi) for every increase in depth of 25
feet (ft). The pressure at the surface of the water is 15 psi. Rounded to the nearest foot, at
what depth will the pressure acting on the object be 50 psi?
