100 showers before dinner.

At the start of the week the leaders needs to put their math thinking caps on to decide on an efficient shower rule! When work is finished around 4, dinner is served at 6 and most people want to shower in between, 10 minutes showers aren't an option! Accomodating for 100 people showering resulted in a mandatory 2 minute rule-including dressing and undressing in the shower trailer! Surprisingly it worked pretty well, but the question of-"How many minutes can each shower be in order for 100 people to shower in 2 hours?"- was the trick, or essential math, for clean and happy people!
