She ran 2 miles because you have to multiply 3 laps by 2/3. It already gives you the total for 1 mile so you don't need to do any division all you have to do is multiply and you get 2 miles.
Assuming that "x" symbol indicates multiplication, the answer should be 4/3. If you need the decimal form, it would be 1.3. If you want the mixed number form, it'd be 1 1/3.
