Final answer:
Clients should arrive ahead of their appointments based on the time it takes to complete consultation cards, considering the average arrival rate of customers.
Step-by-step explanation:
When it comes to scheduling appointments and client management, understanding the average time between customer arrivals can help businesses optimize their schedules and reduce wait times. If we're expecting 30 customers to arrive per hour, this means one customer arrives every two minutes, on average. Therefore, assuming a client needs to complete a consultation card before their appointment, they should be advised to arrive accordingly. If a consultation card takes a certain amount of time to fill out, this should be factored into the time the client is asked to arrive before their appointment.
For instance, if we use the information that it takes six minutes on average for three customers to arrive, a single client might be advised to arrive roughly that amount of time ahead if that is how long it takes to complete the consultation card. This ensures they're attended to promptly at their scheduled appointment time.
