Sente, Violet, Scarlett and Kurt have spent the day hiking in the hills to the south of the city. One the way home they come across a rickety old bridge thats only strong enough for two of them to cross at the same time. The light is fading fast and so they need to use a flashlight everytime they make a crossing. The bridge is too long and narrow to throw the flashlight across, so someone will always have to carry it back and forth. Sente was injured earlier in the day and will take 10 minutes to cross the bridge, Scarlett can cross in 5 minutes, Kurt in 2 minutes and Violet in 1 minute. A storm is brewing and they cant waste any time. Kurt thinks for a moment and claims they can all cross the bridge in just 17 minutes, HOW?
