On the map with the scale of 0.50/kloc-0.00/kloc-0.50 km, indicate that a unit is 50 km.

That is, the scale: 1cm: 50km.

So the distance is 4.6cm, which means 4.6*50=230km.

The actual distance between the two places is 230 kilometers.

I wish you progress in your studies and go up a storey still higher! (*^__^*)
