$\dfrac{4}{9} \text{ meals per minute}$
Determine the increase in the number of meals served: $=67−47=20$ Determine the time: $=9:15−8:30=45$ minutes The serving rate can be computed by dividing the number of meals served by the time: Serving Rate = $\dfrac{20 \text{ meals}}{45 \text{ minutes}}=\dfrac{4}{9} \text{ meals per minute}$
