Answer:
The maximum fuel economy of the car is 25.57225
Step-by-step explanation:
we are given

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
The answer is 30 minutes. Because 6 x 5 = 30 while 5 6 = 30 as well. Hope this helped.
