Question 10
A queue builds at a constant rate outside a museum that opens at 10:30 AM. If 3 entrances open, the queue clears at 10:39 AM; if 5 entrances open, it clears at 10:35 AM. At what time did the first visitor start queueing?
Use the usual continuous-rate model: all entrances have equal constant admission rates, and arrivals continue at the same rate after opening.
