Partial differentiation of a function with more than one variables refers to its derivative being taken with respect to one of those variables, while the rest being held as a constant.
An example is the volume of a cylinder given by:

The volume requires two variables in order to work out the volume, namely the radius and the height.
Using partial differentiation, its partial derivative can become:

This symbol is used in place of the derivative symbol, in order to distinguish total derivatives and partial derivatives.

Graph in desmos by making a table then you're able to count more clearly
10,080,000 (because 720×14, the total number of days he swam in two weeks, is 10,080 and then you divide it by .001, the number of kilometers in one meter, which gives you 10,080,00.)
