In this question, we're trying to find the depth of the fish after 12 seconds
We know that the fish descends at a rate of 18 in. per second.
We need to represent this as an equation
Our equation would be:
y = -18x
x = seconds of descending
y = depth
We don't know where the fish started, so we can assume that it started at a depth of 0
Plug in 12 to the equation and solve:
y = -18(12)
y = -216
The fish would be at a depth of -216 inches.
Answer:
-216 inches
