Mike is testing new batteries to determine if the batteries last as long as advertised. The actual life of one of the batteries was only 4 weeks, 2 days, and 13 hours even though the advertisement claimed it would last 3,000 hours.

What was the difference, in HOURS, between the advertised life of the battery and the actual life of the battery?
