Question

Two divers are scuba diving. The first diver is 30 meters under water, which is 12 meters

deeper under water than the second diver. The second diver's depth, d, can be determined
using the equation d + 12 = 30. The gauge on the second diver's equipment says he is 16
meters under water. Is his gauge correct?

Answer 1

d=first diver depth

s=second diver depth

d= 30

S= 30-12=18

the equation given and the gauge must be wrong because the equation for the second duvet souls be s=d-12 since the first diver is DEEPER than the second.
