Taking a stab here - are you referring to a heat transfer problem (T = temperature and t = time)? If so, the rate of heat transfer under conduction can be modeled as being proportional to the temperature difference between the two bodies. Hence
\frac {dT}{dt} = k (\Delta T)
It appears that you have been given information that one of the bodies is held at a constant 5 degrees. Does this help?
