50 km

Explanation:

So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by #2.5/1#. Then, 20 x 2.5=50. So the answer is 50 km
