The introduction to this problem involves modelling a race from one tree to another, and the requirement to touch a fence on the way. The challenge is to determine the point on the fence that should be touched to minimize the distance to run.

Having worked on some specific examples, the next step is to move to the general case. This involves determining the distance to run using Pythagoras’ theorem, and then differentiating the result to find a turning point.
