In a swimming relay race there are four team members and each one swims just one of the strokes: butterfly, backstroke, breaststroke or front-crawl.
You are the swimming coach for the Hungarian team in the Olympics, who should you choose for each stroke based on their current times in seconds?
| Butterfly | Backstroke | Breaststroke | Front-crawl | |
| Adam | 35 | 36 | 36 | 25 |
| Boris | 31 | 31 | 35 | 23 |
| Carl | 33 | 35 | 39 | 26 |
| Dean | 32 | 38 | 33 | 24 |
Remember it is the fastest team that wins!
Once you have tried this yourself you could look here at an algorithm that can be used, hints to try it on excel and the solution.
This one is a bit trickier …
| Butterfly | Backstroke | Breaststroke | Front crawl | |
| Ella | 29 | 34 | 31 | 24 |
| Freya | 32 | 28 | 30 | 25 |
| Grace | 30 | 33 | 27 | 26 |
| Holly | 31 | 29 | 32 | 23 |
