Question

On a certain day, the temperature changed at a rate of -2°F per hour. How many hours did it take for the change in temperature to be -12°F?

Answer 1

It took 6 hours for the temperature to change by -12°F with a rate of -2°F per hour.

Step-by-step explanation:

To find the number of hours it took for the temperature to change by -12°F with a rate of -2°F per hour, we can set up an equation. Let x represent the number of hours. The equation will be:

-2(x) = -12

Divide both sides of the equation by -2:

x = 6

Therefore, it took 6 hours for the temperature to change by -12°F.
