The sprinter brain teaser from mathematician Chris Seber may require a pencil and paper to figure out. Can you solve his sprinter brain teaser? Here's the puzzle: There are 25 sprinters, and only 5 sprinters can run in a single race. You can assume that a sprinter gets the same finish time every race. For example, if runner A runs his first race in 10.5 seconds, he will run his second race in 10.5 seconds as well. In only seven races, can you find the fastest three sprinters without a stopwatch? Watch the video below to see if this is possible.
