Answer:

7 hours

Step-by-step explanation:

We are given that

At sunset, the temperature=-5 degrees Fahrenheit

Each hour, temperature falling=2degrees Fahrenheit

We have to find time taken to reach the temperature -19° F.

Let x be the time time taken to reach the temperature -19° F

According to question

-5+x(-2)=-19

Where we taking 2 negative because temperature decreases.

-5-2x=-19

-5+19=2x

14=2x

x=\frac{14}{2}

x=7

Hence, it will take 7 hours for the  temperature to reach -19° F.
