Aman paddles a canoe in a long, straight section of a river. the canoe moves downstream with constant speed 3 m/s relative to the water. the river has a steady current of 2 m/s relative to the bank. the man's hat falls into the river. four minutes later, he notices that his hat is missing and immediately turns the canoe around, paddling upriver with the same constant speed of 3 m/s relative to the water. how long does it take the man to row back upriver to reclaim his hat?
