Hmmmm...Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.
Assume that penguins live with a density of 1,000 penguins per square mile and can run at an average speed of 7 miles per hour on land and swim at 20 miles per hour. Also assume that a polar bear has a territory of 10 square miles, can run at 25 miles per hour and swim at 10 miles per hour.
How many penguins will an average polar bear eat in any given month, remembering that a polar bear could, as a maximum, only eat one penguin per hour and 7% of the land is next to the sea.
AnswerNone. Polar bears live at the North Pole and penguins live at the South Pole.
