Question

18. The temperature was

40° at noon. At midnight the
temperature was -10°.
Which integer describes the
change in temperature?
PLEASE ANSWER

Answer 1

• t_1=40
• t_2=-10

`\boxed{\sf \Delta T=t_2-t_1}`

`\\ \sf\longmapsto \Delta T=-10-40`

`\\ \sf\longmapsto \Delta T=-50°C`

Answer 2

The change in temperature is -50

Explanation:

Take the second temperature and subtract the first temperature

-10 -40

-50

The change in temperature is -50
