Question 17
People join a concert-hall queue at a constant rate. Gates open at 7:35 PM. Three admission gates would clear the queue by 7:44 PM; five would clear it by 7:40 PM. If the first person began queueing at $A:BC$ PM, find $A-B+C$.
Use the standard continuous-rate model, with identical admission rates at every gate.
