Within the context of the two problems above, what is the difference between ``dry cat food'' and ``water?'' {{CMD_55}} If we write the amount of dry cat food as a function of time, this function is not continuous. The reason it isn't continuous is that the dry cat food is a collection of individual kibbles, which are eaten whole. On the other hand, if we write the amount of water as a function of time, this function is continuous. {{CMD_56}} {{CMD_57}}
