Tired of complicated inter-jurisdictional swinekeeping legislation, Farmer Joe has converted his pig farm into a restaurant. Farmer Joe's BBQ Porkatorium is now the premier pig-themed eatery in Oddsville.Farmer Joe's secret is his ability to cook pork chops in record time, despite the tiny size of the kitchen's pork grill.

Nevertheless, when three customers simultaneously order the Porkgasm Surprise, Joe is able to prepare it surprisingly quickly. What is the fastest time in which Joe can complete the grilling of three pork chops on his pork grill?
