5 feet
OK lets do a comparison in this term, Can a 5 yr old human child swim as far and as long as an professionally trained adult Olympic long distance swimmer? So... no. I dont think you can compare an adult and a cub.
The female polar bear lives with her cubs for more than two years. By that time they are weaned and have learned how to hunt and look after themselves. The male polar bear does not live with them. In fact, male polar bears have been known to kill cubs.
Polar bears can swim for hundreds of miles without stopping as they have been spotted out at sea hundreds of miles awat from any ice or land.
Polar bears often travel hundreds of miles to find food.
2 miles a way
about 5 feet
Polar Bears require a great area to support themselves therefore they travel far and spread their species throughout the north. There is only one species.

The polar bear is the only mammal in North America that will actively hunt human beings. A Polar Bear can take a human head off with a single blow of its paw. Polar bears have very sensitive noses and can smell blood as far as 20 miles away.
black bears - up to 60 mph but grizzly bears can swim forever apparently. and they can swim for up to a minute underwater (:
There are far too many variables here to be able to answer this question.
Global warming is melting ice caps and pushing others far apart, making it hard on polar bears to form any sort of residency and threatening their overall habitat. Polar bears are having trouble maintaining their weight because of lower food supplies and the need to swim further to get to glaciers.
It is highly unlike that a polar bear would even get a chance to kill a moose because these animals live in two entirely different biomes. You would not see a polar bear in the boreal or transition-boreal forests, nor would you find a moose in the arctic near the coastline. For that reason, no a polar bear would not nor could not kill a moose. However, as far as human-ability to be very imaginative, it is likely that a polar bear could kill a moose.
