The average change in temperature from 9 a.m to 9 p.m is - 0.6 °
per hour (negative indicates temperature decreases), if the temperature at 9 a.m was 13.6 °
and the temperature at 9 p.m was 6.4 °
.
Step-by-step explanation:
The given is,
The temperature at 9 a.m was 13.6 °
The temperature at 9 p.m was 6.4 °![C](https://tex.z-dn.net/?f=C)
The temperature at 3 a.m was 23.5 °![C](https://tex.z-dn.net/?f=C)
Step:1
Hours difference between 9 a.m to 9 p.m is,
= 12 hours (∵ consider a clock for this calculation)
Step:2
Temperature difference between 9 a.m to 9 p.m is,
= 6.4 - 13.6
= - 7.2 °![C](https://tex.z-dn.net/?f=C)
Step:3
Average change in temperature between 9 a.m to 9 p.m,
![Avg = \frac{Temperature difference}{Time period}](https://tex.z-dn.net/?f=Avg%20%3D%20%5Cfrac%7BTemperature%20difference%7D%7BTime%20period%7D)
![= \frac{- 7.2}{12}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-%207.2%7D%7B12%7D)
= - 0.6 °
( ∵ Negative indicates temperature reduction)
Result:
The average change in temperature from 9 a.m to 9 p.m is - 0.6 °
per hour ( Negative indicates temperature reduction).
