A hotel hosts banquets for conferences in a large ballroom with tables of ten. Servers must get the meals from the kitchen, bring them out to the tables, and then place the meals on the tables. It takes three minutes to get the meals, bring them out to the tables, and then $18$ seconds to serve each guest.
