Respuesta :

4 miles is longer than 4 km and they are not the same size

Answer: (b) 4 mi

Explanation:

    We will convert both options to a singular unit.

4 km ≈ 2.49 miles

    Now, we can more easily compare them.

4 miles ? 2.49 miles

4 miles > 2.49 miles

                  b, 4 mi is larger
