Hot coffee

The speed of cooling of the coffee or warming of the milk depends not only on the mass of the liquids, as Gokul has pointed, but on the difference in temperature between the liquid and the ambient air and on the area of the surface of the liquid in contact with the air.
Without knowing all this variables, it is impossible to give an answer, but intuitively I think the mixed coffee will be only slightly above ambient air temperature and will cool slowly.
