Question

On the coldest day of the year, the temperature at noon was 11℉. By midnight, the temperature had decreased by 15.5℉. What was the temperature at midnight? *

Answer 1

Answer: -4.5 ℉

Explanation:

Given: On the coldest day of the year, the temperature at noon = 11℉

By midnight, the temperature had decreased by 15.5℉.

i.e. The temperature at midnight = Temperature at noon - 15.5℉

= 11℉ - 15.5℉

= (11-15) ℉

= -4.5 ℉

Hence, the temperature at midnight was -4.5 ℉.
