What is the change in temperature between −20°F and 30°F
The change in temperature between -20°F and 30°F is 50°F.
To find the change in temperature between -20°F and 30°F, we subtract the initial temperature (-20°F) from the final temperature (30°F).
30°F - (-20°F)
To subtract a negative number, we can rewrite it as adding the positive value:
30°F + 20°F
Now we can perform the addition:
30°F + 20°F = 50°F
Therefore, the change in temperature between -20°F and 30°F is 50°F.
