Answer:
1.333 customers per hour
Explanation:
The computation of average customer turnover is shown below:-
number of customers processed per hour = 1,500 ÷ 15
= 100 customers per hour
Now,
Average time spend by the customer is given as the ratio I/R = 75 ÷ 100
= 0.75 hours
or
= 45 minutes
Customer turnover = 100 ÷ 75
= 4/3
or
= 1.333 customers per hour
