A petrol pump is opening a customer service centre which will be having only one counter to attend to the people. The manager estimates that the customers will arrive at the rate of 25 per hour. The customer care executive who has been considered for the post can attend customers at the rate of 1 customer every 2 minutes. Assuming Poisson arrivals and exponential service, calculate the average waiting time of the customers.
