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

216 inches / 18 feet

Step-by-step explanation:

Multiply the descension by the number of seconds.

18*12 = 216 inches, or 18 feet.

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
