Hi,
Here is the problem
A car travels 25 miles/gal in the city and 40miles/gal on the highway. Which is closest miles per gallon that car averages if it travels 10miles in city and 50 miles on the highway?

The answer is 36

If anybody can help me with the step in order to achieve the answer, I would greatly appreciate it
