Question

A woman drives an SUV that gets 11 ​mi/gal (mpg). Her husband drives a hybrid that gets 65 mpg. Every​ week, they travel the same number of miles. They want to improve their combined mpg. They have two options on how they can improve it.

Answer 1

Answer:

The correct solution is "$(45.5>39) \ mpg$". A further explanation is provided below.

Step-by-step explanation:

The above query seems to be incomplete. Below is the attachment of the complete question is attached.

Given that,

For SUV,

= 11 ​(mpg)

For hybrid ghost,

= 65 mpg

Now,

Option 1:

After tuning, the mileage of SUV will be:

= $11+2$

= $13 \ mpg$

Average mileage will be:

= $\frac{13+65}{2}$

= $\frac{78}{2}$

= $39 \ mpg$

Option 2:

Given:

Mileage of new hybrid,

= 80 mpg

Now,

Average mileage will be:

= $\frac{11+80}{2}$

= $\frac{91}{2}$

= $45.5 \ mpg$

Thus we can say that the second option gives better mpg as compared to the first one.

i.e.,

⇒  $(45.5>39) \ mpg$
