Answer for < 3 (correctly)

For the first problem, you can multiply each of their distance from school by the how far they are to get how much they walked. Randy would look like this:

So he walks 4 miles. Sasha would look like:

This means Sasha walks 4 miles as well.
Julie's would look like this:

Julie also walks 4 miles.
From this, we can see that C is the only correct statement.

As for the second, the number 3.444444... would be considered a real and rational number because you can make it a fraction sort of like 1/3 and 0.33333..., so it would be a rational number. A real number is any number that doesn't have a imaginary variable next to it, so it would also be real.
