Car averages x miles per gallon means that 1 gallon is enough to drive 36 miles.

We are asked to find average miles per gallon (miles/gallon) --> average miles per gallon would be total miles driven divided by total gallons used (miles/gallon).

Total miles driven is 10+50=60.

As a car averages 25 miles per gallon in the city for 10 miles in the city it will use 10/25=0.4 gallons

What is the average value?

A data set, the arithmetic mean, also known as arithmetic average, is a measure of the central tendency of a finite set of numbers: specifically, the sum of the values divided by the number of values.

As a car averages 40 miles per gallon on the highway for 50 miles on the highway it will use

50/40=1.25 gallons;

So average miles per gallon equals to

[tex]=\frac{10+50}{0.4+1.25}\\=36[/tex]

Therefore option D is correct.
