Final answer:
The hourly arrival rate when the average time between customer arrivals is 1.50 minutes is calculated by dividing 60 by 1.5, resulting in a rate of 40 customers per hour.
Step-by-step explanation:
The student is asking to calculate the hourly arrival rate given an average time between customer arrivals. If the average time between customer arrivals is 1.50 minutes, convert this time into hours by dividing the number of minutes in an hour by the average time per arrival. One hour has 60 minutes, so dividing 60 by 1.5 gives us the hourly arrival rate.The calculation is as follows: 60 minutes per hour รท 1.5 minutes per arrival = 40 arrivals per hour. Thus, the hourly arrival rate is 40 customers per hour.Conclusion: The hourly arrival rate, when customers arrive every 1.5 minutes on average, is 40 customers per hour.
