Question:
What is the average flow rate in cm{eq}^3 {/eq}/s of gasoline to the engine of a car traveling at 63 miles per hour if it averages 39 miles per gallon? cm{eq}^3 {/eq}/s
Fuel Economy.
If we divide the speed of an automobile by the flow rate of fuel consumed by the engine, we get the performance of the car. This parameter has become very important due to the high prices of gasoline and the pollution produced by burning it.
