What is the difference in temperature between −10°F and 30°F?

The difference in temperature between −10°F and 30°F is 40 degrees Fahrenheit.

To find the difference in temperature between -10°F and 30°F, you can subtract the lower temperature (-10°F) from the higher temperature (30°F):

30°F - (-10°F)

Simplifying the subtraction:

30°F + 10°F

Resulting in:

40°F

Therefore, the difference in temperature between -10°F and 30°F is 40°F.
