Find the change in temperature from - 1 f to - 20 f

-19 F

Step-by-step explanation:

Change in temperature is simply the final temperature - initial temperature

in this case, final temperature is - 20F and initial temperature is - 1F

Change in temperature,

= Final temp - Initial temp

= - 20 - (-1)

= - 20 + 1

= - 19 F
