Consider a single-server queueing system where customers arrive exactly 50 minutes apart. 

1. Find the average total waiting time assuming it takes exactly 30 minutes to serve each customer.
2. Find the average total waiting time assuming it takes an average of 30 minutes to serve each customer, with a standard deviation of 60 minutes.
3. Find the average total waiting time assuming service is a two-part process: the first part is exponentially distributed with mean 20 minutes, and the second part is exponentially distributed with mean 10 minutes (independent of the first part). Assume that the second part begins as soon as the first part is complete.
