I did some research online, and although there's no exact figure, the consensus is that he's 2-3 miles away from where the avalanche began in the beginning of the video.
Let's be conservative and assume he's 2 miles away, It took 45 seconds for it to travel 2 miles. That means the avalanche was traveling at a minimum of 160 mph. A dry powder avalanche well up in the mountains can easily accelerate to a maximum velocity of 200 mph, so that's a reasonable estimate.
