Afish 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.

-216 inches

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
