After observing arrivals and departures at a highway toll booth over a 60-minute time period, an observer notes that the arrival and departure rates (or service rates) are deterministic, but instead of being uniform, they change over time according to a known function. The arrival rate is given by the function, ?(?) = 2.2 + 0.17? − 0.0032?^2, and the departure rate is given by ?(?) = 1.2 + 0.07?, where t is in minutes after the beginning of the observation period and ?(?) and ?(?) are in vehicles per minute. Determine the total vehicle delay at the toll booth and the longest queue, assuming D/D/1 queuing.

Vehicles are known to arrive according to a Poisson Equation at a specific spot on a highway. Vehicles are recorded at 25-second intervals, with 250 of these intervals being 25-second intervals. In 25 of the 250 periods, 3 automobiles have arrived. Estimate the number of these 250 intervals in which four automobiles arrive at the same time. solve and show your complete solution please.
