Question

The temperature at 8:00 a.m. was –6°F. By 4:00 p.m. the temperature was 17°F. What was the change in temperature from 8:00 a.m. to 4:00 p.m.?

Answer 1

It went up 23 Fahrenheit

Answer 2

`23^(\circ)F`

Explanation:

We have been given that the temperature at 8:00 a.m. was –6°F. By 4:00 p.m. the temperature was 17°F. We are asked to find the change in temperature from 8:00 a.m. to 4:00 p.m.

The change in temperature would be final temperature minus initial temperature.

`\text{The change in temperature}=17^(\circ)F-(-6^(\circ)F)`

`\text{The change in temperature}=17^(\circ)F+6^(\circ)F`

`\text{The change in temperature}=23^(\circ)F`

Therefore, the change in temperature from 8:00 a.m. to 4:00 p.m. is 23 degree Fahrenheit.
