The table below provides the time stamps for the 8 people who called a reservation desk for a ferry service between 8:00 am and 8:20 am. Based on the data in the table, what is the flow rate of callers?

- Caller 1: Time in = 8:01, Time out = 8:05
- Caller 2: Time in = 8:02, Time out = 8:07
- Caller 3: Time in = 8:06, Time out = 8:08
- Caller 4: Time in = 8:09, Time out = 8:12
- Caller 5: Time in = 8:10, Time out = 8:15
- Caller 6: Time in = 8:12, Time out = 8:20
- Caller 7: Time in = 8:16, Time out = 8:19
- Caller 8: Time in = 8:17, Time out = 8:19

Answer :

Final answer:

The flow rate of callers is 24 callers per hour, calculated by dividing the total number of callers (8) by the time interval in hours (1/3 hour).

Explanation:

To calculate the flow rate of callers to the ferry reservation desk, one must first establish a time interval during which the calls were monitored. According to the question, this interval is between 8:00 am and 8:20 am, which is 20 minutes or 1/3 of an hour. Given that there are 8 callers within this time frame, the flow rate can be calculated by dividing the total number of callers by the total time in hours.

To find the flow rate, use the following formula: Flow Rate = Total Number of Callers / Total Time in Hours. In this case, the flow rate would be 8 callers divided by 1/3 of an hour, which would be:

Flow Rate = 8 callers / (1/3 hour) = 24 callers per hour.
