pervisor: “Last week, you spoke with 800 customers in 40 hours.” mployee: “That is an average of __ customers every 30 minutes.” 5 10 15 20 25
The Correct Answer and Explanation is:
To calculate the average number of customers the employee spoke with every 30 minutes, we need to divide the total number of customers by the total time spent, and then adjust for the 30-minute intervals.
Step 1: Calculate the number of customers spoken to per hour
The supervisor mentioned that 800 customers were spoken to in 40 hours.
To find the number of customers per hour, divide 800 by 40:Customers per hour=800 customers40 hours=20 customers per hour.\text{Customers per hour} = \frac{800 \text{ customers}}{40 \text{ hours}} = 20 \text{ customers per hour}.Customers per hour=40 hours800 customers=20 customers per hour.
Step 2: Adjust for 30 minutes
Now, since the question asks for the number of customers spoken to every 30 minutes, we need to divide the number of customers per hour by 2, because 30 minutes is half of an hour.Customers per 30 minutes=20 customers per hour2=10 customers.\text{Customers per 30 minutes} = \frac{20 \text{ customers per hour}}{2} = 10 \text{ customers}.Customers per 30 minutes=220 customers per hour=10 customers.
Conclusion:
The employee spoke with an average of 10 customers every 30 minutes. So, the correct answer is 10 customers.
Explanation:
This calculation works under the assumption that customer interactions are evenly distributed across the 40 hours. By breaking down the total number of customers per hour and then adjusting for half an hour (30 minutes), we arrive at the average number of 10 customers per 30 minutes.
