Question

one winter day,the temperature ranged from a high 20°F to a low -25°F. By how many degrees did the temperature drop?

Answer 1

45 degrees. 20 - (-25)

Answer 2

`45^(\circ)F`

Explanation:

We have been given that one winter day,the temperature ranged from a high 20°F to a low -25°F.

To find the degrees by which temperature dropped, we will find difference between the final temperature and initial temperature.

`-25^(\circ)F-20^(\circ)F=-45^(\circ)F`

Since our difference is negative, therefore, the temperature dropped 45 degrees Fahrenheit.
