Question

Prompt

At a depth of

h

meters below the surface, the estimated total pressure

P_{1}

, in kilopascals (kPa), a diver experienced is given by

P_{1} = 10 h + 101

, which is a combination of estimated water pressure and estimated atmospheric pressure. After maintaining a certain depth, the diver descended

d

additional meters. The estimated total pressure

P_{2}

in kPa, the diver experienced after descending these

d

additional meters is given by

P_{2} = 10 d + 311

. Which of the following is the best interpretation of

311

in this context?

The estimated total pressure, in kPa, the diver experienced at a depth of d meters

The estimated increase in the total pressure, in kPa, the diver experienced for each increase in the depth by 1 meter

The estimated increase in the total pressure, in kPa, the diver experienced for each increase in the depth by d meters

The estimated total pressure, in kPa, the diver experienced when the diver began to descend d additional meters
