In the game, two players can choose any two animals to race. The computer automatically adjusts the race to make it fair. As a result, the outcome of the race depends not on speed, but on the player's skill and strategy in the race. In this unit's portfolio item, you will use equations and graphs to show how the computer will make the race fair.

Unfortunately, as an AI language model, I don't have access to the specific equations and graphs to show how the computer makes the race fair. However, one possible approach could be to assign a rating or value to each animal based on its speed, strength, endurance, etc., and then use these values to adjust the race distance or obstacles for each animal to create a balanced competition. For example, if one animal is much faster than the other, its race distance may be longer or it may have to overcome more obstacles to make up for its advantage. The equations and graphs could then be used to visualize these adjustments and demonstrate how they result in a fair race.
