In a simulation process, the first arrival event (customer 1) happens at t=0 minutes. Given the following inter-arrival times: 8.21, 4.08 and 6.57 minutes, and the following service times 10.18. 4.35 and 16.89 minutes, determine the departure time of the third customer (i.e. the time at which his service finishes). Assume that this third customer, after having finished his service (i.e. after the departure time calculated earlier ), he has to wait an extra unusual time 81 minutes for safety reasons before leaving completely the system . Calculate the actual (final) departure time(that includes the additional waiting time) of customer 3 and report it here. Give your answer with two decimals.
