In a machine station, jobs arrive according to a Poisson process
with a rate of 8 per hour. There are only two types of jobs
processed in this station, Job A and Job B. The probability that a
job is Job A is 2/5. If it is Job A, it takes exactly 15 minutes to
process it. If it is Job B, it takes exactly 5 minutes to process
it. On average, how long each job stays in the station?
(Hint: M/G/1 queueing system)
