There is a single gate at an entrance to a recreational park where arriving vehicles must stop to pay their tickets. The park opens at 8:00AM, at which time vehicles begin to arrive at a rate of 480 veh/hr. After 20 minutes the arrival flow rate declines to 120 veh/hr, and it continues at that level for the remainder of the day. If the service time is 15 seconds per vehicle, and assuming D/D/1 queuing, determine the Longest Vehicle Delay in mins.

Transpo Engineering
There is a single gate at an entrance to a recreational
park where arriving vehicles must stop to pay their
tickets. The park opens at 8:00AM, at which time
vehicles begin to arrive at a rate of 480 veh/hr. After
20 minutes the arrival flow rate declines to 120 veh/hr,
and it continues at that level for the remainder of the
day. If the service time is 15 seconds per vehicle, and
assuming D/D/1 queuing, determine the Longest
Vehicle Delay in mins.
Note: Round off your answers to the nearest whole
number. Only include the numeric value of your answer
without the unit (i.e. 22).
