Step-by-step explanation:
The way to find missing numbers in equivalent ratios is to multiply the means (the first denominator and the second numerator) and multiply the extremes (the first numerator and the second denominator). It sounds really complicated, but it is quite simple =)
2/5 = x/10
The means in this equivalent ration are 5 and x. The extremes are 2 and 10.
5x = 20
Now solve =)
x = 4
That was pretty simple. Let's move on to the next one. Do exactly the same thing here:
4/10 = 6/x
60 = 4x
15 = x
That was pretty simple, too! Keep going!
6/15 = x/25
15x = 150
x = 10
All of these should be equal, so check them by dividing:
2/5 = 0.4
4/10 = 0.4
6/15 = 0.4
10/25 = 0.4
They all check out, so these are your answers: 2/5, 4/10, 6/15, 10/25
I really hope this helps you =)

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
