Since we're looking for the rate of kilograms per minute, we can represent the rate as [tex]R \frac{kg}{min}[/tex]. We just need to divide the kilograms crushed by the time it takes to crush them to obtain R: [tex]R \frac{kg}{min}=\frac{13/4}{3/4} \frac{kg}{min}=\frac{13}{3} \frac{kg}{min}=4\frac{1}{3} \frac{kg}{min}[/tex]
