Here is a potential solution to this problem.
Let "t" represent the difference between Kant's clock and the Schmidt's clock (the correct time) in minutes. Let "x" represent the amount of time it takes for Kant to walk from his house to Schmidt's.
For illustration, let us assume a concrete case: t = 60 mins, and x = 30 mins. Suppose Kant leaves his house at 1pm according to his clock, and stays at Schmidt's place for 2 hours.

Event | Kant's Clock | Schmidt's Clock |
---|---|---|
Leaves Home | 1:00 | 2:00 |
Arrives at Schmidt's | 1:30 | 2:30 |
Leaves Schmidt's | 3:30 | 4:30 |
Arrives Home | 4:00 | 5:00 |
Since Kant knows his algebra he sets up a simple system of equations. The first equation can be set by observing in sloppy notation that 1:00 + t + x = 2:30. Since "t" and "x" are measured in minutes this is better represented as t + x = 90.
Similarly, 4:30 - t + x = 4:00, can be recast as x-t = -30.
Adding the two equations gives t = 60 and x = 30.
This can be easily generalized.
