A fish descends at a rate of 18 inches per second. What is the depth of the fish after 12 seconds?

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

216 inches / 18 feet

Step-by-step explanation:

Multiply the descension by the number of seconds.

18*12 = 216 inches, or 18 feet.
