Calculate the capacity of a teller based on your assumption

Calculate the capacity of a teller based on your assumption ofhow much time does an average teller take to serve an average customer and onthe assumption that each teller could service two lanes [for example, if anaverage customer is served in 5 minutes, then 12 customers can be served in anhour]. Assume that an average teller works at 80% capacity utilization, then howmany tellers (both full time and part time) should be scheduled for each shift.
