Answer:
[tex]\boxed {\tt -4 \textdegree \ per \ hour }[/tex]
Step-by-step explanation:
This question asks us to find the average rate of change in temperature per hour.
Therefore, we must divide the temperature change by the hours.
[tex]rate \ of \ change =\frac{temperature \ change}{hours}[/tex]
The temperature dropped 24 degrees in 6 hours. Since it dropped, the change was negative.
[tex]temperature \ change = -24 \textdegree \\hours = 6 \ hours[/tex]
Substitute the values into the formula.
[tex]rate \ of \ change =\frac{-24 \textdegree}{6 \ hours}[/tex]
Divide.
[tex]rate \ of \ change = - 4 \textdegree / hour[/tex]
The average change in temperature was -4° per hour. The temperature dropped 4 degrees each hour.
