CONSUMING GAS MILEAGE (DIFFERENTATION)

CONSUMING GAS MILEAGE (DIFFERENTATION)

1. The gas mileage of an automobile is affected by many factors like road surface , tire type , velocity ,fuel octane rating , the speed and direction of the wind . the gas effect of the velocity on the gas mileage of a certain car is expressed in the function below.

2. The maximum or minimum gas mileage is obtained when it rate of change is 0 . The rate of change of the gas mileage is 0 when the velocity is 103.62km/h 0r 38.6 km/h. The gas mileage when the velocity is 103.62 km/h is 11.51 mil/gal, while it's 28.528 mil/gal when the velocity is 38.6 km/h .Therefore , to obtain the best gas mileage when driving this car a velocity of 103.62 km/h should be maintained. ( 1 mil = 1.60934 km )( 1km =0.621371 mil)
