where
where s represents the average speed of the car, measured in miles per hour
So, we have to maximize f(s)
So, firstly we will find derivative
now, we can set it to 0
and then we can solve for s
To find maximum fuel economy , we can plug s into f(s)
So,
The maximum fuel economy of the car is 25.57225
