Acertijo. 2.- A bear walks 10 Km . To the south, 10 east and 10 to the north, back to the point from which he started .

What color is the bear?



Solution Bear color is white , as a polar bear.

The only places where the condition of returning to the starting point is met are the North Pole and any point located 10 km north of the parallel measuring 10 km in circumference , since to do 10 km east back to the point of departure.

In either case we will be one of the poles , so the bear will be white.
