    Im unable to solve this question. A river is flowing downstream at 30km/h relative to the shore. A rafting team is on the raft and at first they row upstream and go only 3km/h relative to the shore. A man at the back of the raft is wearing a hat when they begin, but after 10 min his hat falls into the water (floats) and it is 15 min since it has fallen before they notice. They, then, instantaneously reversed the direction to catch up the hat, rowing with the same strength and power with which they were rowing before. In how much time will they catch the hat?
