Question

If the temperature after 4.4 degree drop was -2.5 degrees Celsius what was the temperature at noon

​

Answer 1

1.9°C

Explanation:

Let X be the temperature at noon and -2.5°C be the current temperature after the drop.

-We calculate temperature at noon as:

`\bigtriangleup =t_o-t_n\\4.4=X--2.5\\\\X=4.4-2.5\\\\=1.5\textdegree C`

Hence, the temperature at noon was 1.9°C
