Answer:
The utilization rate with the minimum number of voters = 0.75
Step-by-step explanation:
Rate of arrival of voters = 27 voters per hour
If each voter spends 5 minutes in the voting booth,
In 1 hour, number of voters = 60/5 = 12. i.e. service rate = 12 voters per hour
Utilization rate, UR=
...............(1)
Maximum value for UR = 1. i.e UR ≤ 1

number of voters cannot take a decimal value, therefore,
The minimum number of voters = 3
Substituting number of voters into equation (1)
