Answer: 3,000 balls per hour
Step-by-step explanation:
Given: The number of plastic balls manufactured by a machine = 24,000
Time taken to manufacture 24,000 plastic balls = 8 hours
To calculate the unit rate , we divide the number of plastic balls by the amount of time taken to produce it, we get
[tex]\text{Unit rate}=\dfrac{\text{Number of plastic balls}}{\text{Time}}\\\\\Rightarrow\ \text{Unit rate}=\dfrac{24,000}{8}\\\\\Rightarrow\ \text{Unit rate}=3,000\text{balls per hour}[/tex]
