Cars travelling to the George Washington Bridge from New Jersey to New York Citymust pay a toll. About 38 percent of the commuters use E-ZPass, which registers thetoll to their account electronically. E-ZPass customers go quickly through the toll areaaveraging a wait time of 30 seconds because of the need to slow down. However, paying customers must queue up at the cash booths. They require an average service timeof twenty seconds each with a standard deviation of 10 seconds. If cars are arriving tothe toll area at an average rate of 8 per minute and there are 3 cash toll booths, what isthe ratio of total time in the system for E-ZPass commuters versus cash commuters?

Question
Cars travelling to the George Washington Bridge from New Jersey to New York City
must pay a toll. About 38 percent of the commuters use E-ZPass, which registers the
toll to their account electronically. E-ZPass customers go quickly through the toll area
averaging a wait time of 30 seconds because of the need to slow down. However, paying customers must queue up at the cash booths. They require an average service time
of twenty seconds each with a standard deviation of 10 seconds. If cars are arriving to
the toll area at an average rate of 8 per minute and there are 3 cash toll booths, what is
the ratio of total time in the system for E-ZPass commuters versus cash commuters?
