1. ## Frozen Waste

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.

I spent far too long thinking about this one, till my son told me the answer, <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">none. A polar bear would have to swim a long way to find penguins!</span hide>

Well done to your son. I had considered calling it A Frozen Waste Of Time but it would have been too much of a giveaway.

Happy New Year!
