Mr. Robertson's flight departs at 6:15pm this evening. He wants to be at the departure gate at least 30 minutes before departure. Mr. Robertson figures it will take him 20 minutes to pack, 35 minutes to drive to the airport, 10 minutes to park, and 30 minutes to get through security. What is the latest time he should start packing for his trip?
