Answer:
<em>7.9</em>
Step-by-step explanation:
<em>I added 2.7 + 2.4 + 2.8, lmk if it's wrong.</em>
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 °
The temperature at 3 a.m was 23.5 °
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 °
Step:3
Average change in temperature between 9 a.m to 9 p.m,
= - 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).
Step-by-step explanation:

x- 10 +10 = 13 + 10
x= 23
