For this case we have that the temperature drops steadily at a speed of [tex]0.8 \frac {degrees} {hour}[/tex], that is, every hour drops 0.8 degrees. So, we can propose a rule of three:
1 hour ----------> 0.8 degrees
x ------------------> 4.4 degrees
Where the variable "x" represents the number of hours that must pass for the temperature to decrease by 4.4 degrees.
[tex]x = \frac {4.4 * 1} {0.8}\\x = 5.5[/tex]
Thus, for the temperature to decrease by 4.4 degrees, 5.5 hours must pass.
Answer:
5.5 hours
