# Paddling Upstream

The Canoe in the River problem is an algebra classic. You know how it goes: “*Paddling upstream, it takes Betty Boater 6 hours to travel up the river to Point Apex. It takes only 3 hours for the return trip downstream to Point Bellows. If the distance between Point A. and Point B. is 15 miles, what would Betty Boater’s speed be in still water?” *

Below is wonderful retelling of the Canoe in the River problem created by Dan Meyer. Using a video camera, an ipod, a quiet morning in a mall, and some great editing, this problem is brought new life in this modern and engaging context.

Check it out at http://blog.mrmeyer.com/?p=7649. Meyer seems to be focused on modernizing mathematics curricula, and the more stuff he does like this, the better.

You’re forgetting to mention the real-life applications of this. Running up the down escalator and down the up escalator is also a great way to workout (and annoy people in the train stations)!
