Bears can swim,  so the premise of the puzzle is flawed.

Math will not help you. Bears are much better at math than we are.

I always ride my bike to the lake, I know about wilderness/predator triathlon.

Dunno about math, but the NY Times just put out a more sensible quiz. basing your odds on bear knowledge:

Could you survive a run-in with a bear? 

There was no "share" button for this one, so hopefully non-subscribers can get past the paywall for one article.

I thought it said Meth.

What's especially fun about sock puppets is that you can make each one unique and individual, so that they each have special characters. And they don't have to be human––animals and aliens are great possibilities

Again the puzzle is based on false information -- not only can bears swim, but they are much faster swimmers than humans. (Micheal Phelps can manage 6 mph, a polar bear 25 mph, even if a grizz is 1/3 the speed of a polar bear, it is still going to get you)

If this puzzle was used as an interview question,  which would be the best response to the puzzle,  ignoring the real world facts and solving the topology question formulated -- or pointing out the flaws in the puzzle premise?

Also if the interviewer took objection to you pointing out the flaws in the premise of the puzzle -- how would this affect the desirablity of employment offered to you?    Does the company reward or punish people that think beyond the narrow constraints offered them?

If the interviewer's response was something like "yeah we know the premise if flawed,  we are just using it to see if you can solve this topological puzzle" that wouldn't be a red flag -- but if it was "Just answer the question" -- this would be a red flag that working there could be unpleasant.

Dude it's just a fun math puzzle, not supposed to be based on reality. They could have chosen robots and aliens. Your last paragraph is right on though. These sorts of brain teasers are no longer favored in tech interviews fwiw.

Dummies! It's a circle! The answer is "infinity"

A really fast swimmer goes about 5 mph.  Record times for 50 meter races are a bit faster than 5 mph because of diving off the block starts and pushing off the walls on flip-turns.

Polar bears can swim a bit faster than the fastest humans, about 6 mph, but no where near 25 mph.

They probably don't build outdoor swimming holes in polar bear country.  wink.gif

25 mph is a polar bear's fastest running speed, not swimming speed. (See link). The fastest swimming speed is reported as 6.2 mph.
