Question

In water, the greater the depth, the higher the pressure.

For every 10 m increase in depth, water pressure
increases by about 100 kilopascals (kPa). At a depth of
40 m, the pressure is approximately 500 kPa.

Write the equation of a linear relation representing the pressure, p, at a depth, d, under water.

Answer 1

P = 10d + 100
