Answer: -20 degrees

Explanation:

The temperature drops 5 degrees/hour.

Find temperature after 4 hours.

Since we are not given a starting temperature, we can only say how much the temperature has dropped after the 4 hours.

5 degrees/hour x 4 hours = 20 degrees

Temperature has dropped so your answer will be negative.
