Question

The pressure, P, measured in pounds per square inch (psi),

on an object under water varies directly with its depth, d, measured in feet. If the pressure on an object at a depth of 20 feet is 8.6 psi, what is the pressure on an object at a depth of 25 feet?
A. 9.85 psi
B. 10.75 psi
C. 13.60 psi
D. 6.88 psi

Answer 1

10.75 psi i'm pretty sure

Explanation:

i'm not sure if this will make sense though

p=kd <-direct variation

8.6 = k × 20 p= .43d

k= .43 p= .43 (25)

=10.75psi
