Baseball Diamond Rate of Change

The video tutorial addresses the baseball diamond problem, where a player runs from second to third base at 20 feet per second. The task is to determine the rate at which the distance between the player and home plate changes. The field is a square with 120-foot sides, forming a right triangle with the player's path. The tutorial explains how to calculate the rate of change using derivatives, resulting in a rate of -7.69 feet per second.
