Answer:
\(T=T_{0} -3h\)
Step-by-step explanation:
Let \(T_{0}\) be the initial temperature and T be the current temperature.
Let h be the number of hours.
In 4 hours, the temperature has been going down 12 degrees.
In 1 hour, it has been going down 12/4 = 3 degrees.
In h hours, it has been going down 3h degrees.
So, the expressions that models this situation is:
\(T=T_{0} -3h\)
