Suppose you are the manager of a horse racing event. You have 25 horses available to race, and each of them runs at a different constant speed. Unfortunately, the track only has 5 lanes, which means you can only race up to 5 horses at a time, and you have no stopwatch: a race only tells you the finishing order of the horses in it. Your objective is to find the top 3 fastest horses, in order. What is the minimum number of races needed to guarantee achieving this goal?
