Question

Hari and Ravi can paddle a canoe across Sirpur Lake at a steady rate of 3 miles per hour. Khan River flows into the lake at the rate of 2 miles per hour. Hari and Ravi paddled their canoe up the river till a gnarled stump when they noticed one of their canteens missing. They turned and paddled downstream, recovered the floating canteen, and again paddled upstream. When they again reached the gnarled stump, Hari said, "It's been just an hour since we last turned around." How many minutes had the canteen been floating in the river?
