Julia ran 37.7 miles less than Stefan last week. julia ran 5.5 miles. How many miles did Stefan run?

37.7+5.5 = 43.2 miles. Feel free to correct.

In the given question it is given that Julia had run 37.7 miles less than Stefan. It is also given that Julia had run a distance of 5.5 miles.

Let us assume that Stefan had run a distance = x

Then Julia ran for a distance = (x - 37.7) miles

Now we get the equation to solve the distance ran by Stefan

x - 37.7 = 5.5

x = 5.5 + 37.7

= 43.2

So Stefan ran for a distance of 43.2 miles.
