For most automobiles, the number of miles per gallon decreases as highway speed increases. Fuel economy drops as speeds increase from 55 to 65 mph, then decreases further as speeds increase to 75 mph. Explain why this is the case.
Solution Step 1 Listing the factors which will affect the fuel economy of a vehicle 1. The engine performance. 2. Speed of the vehicle 3. Shape of the vehicle. There are so many other factors but, we have taken an ideal vehicle with no performance issues. Step 2 Vehicle moving with low speed (less than 30 mph) If the engine performance is moderate and there is no gear shifting takes place, the speed of the vehicle will be low. The fuel consumption of the vehicle will be high and the distance travelled will be short due to insufficient speed.
