Their customers send jobs that arrive, on average, every 3 hours. The standard deviation of the interarrival times is 5 hours. Executing each job takes, on average, 2 hours on the supercomputer and the standard deviation of the processing time is 3.8 hours. On average, how long will it take to finish a job (from the time it is submitted by the customer until the time it is completed)? Note: Do not round intermediate calculations. Round your answer to 1 decimal place.
