Distance between cities

This program lets you practice geography by featuring two tests related to distance between cities.

The first test shows 10 questions where you will have to answer the distance between two cities in kilometers. The score for every answer depends on the ratio between the distance you specified and the true one.

In the 10 questions of the second test, the program shows six cities. Starting from the first city you have to arrive to the last one through the other four cities. You will have to reorder these intermediate cities so the total distance is minimized. Then, the program shows all 24 possibilities in which cities can be ordered, ordered according to distance traveled. The score is higher if the specified order is near the top of the table generated by the program.

In both tests there are two levels of difficulty. At the easy level, the program shows the countries that correspond to the cities, while at the difficult level the countries are not shown.

You can download the source of the current program and the old sum of four cubes applet from GitHub.

unbelievable! excellent! very good OK not so bad, so-so, bah hhhmmmm... poor Yeeech!! Argggh!!
I should tell you something against my principles: Congratulations! Almost perfect. ALMOST. Next time you will perform worse. Apparently you know geography (or you are lucky). Continue playing, this game is for you. Obviously, you need to practice (several months, ha, ha). It seems that you hate geography. You will perform better playing a role player video game.
