So, when doing this kind of problems, the first thing that we would want to do is to add up (all) the numbers first, and by doing this, it would look like the following:

Then, we would then divide it by how many numbers they are.

Your answer:
7
answer: 9
the answer is 9 because 6 ÷ 2 = 3, and if you multiply 3 with 3, you get 9. you multiply the number 3 because you need to find out the distance in miles, and since in inches it is 3, you need to multiply by 3 because that is the formula to get miles.
You got this you can do it I don’t know the answer but I hope you find someone who does(:
