3. Two speadboats can each travel at V= 5 m/s with respect to water. One boat crosses the river of the width l=1000 m by moving strictly perpendicular from point A to point B and back. Water flows at u=0.5 m/s as shown. The second boat is moving along the center of the river from points C to D and back, distance s=1000 m. a) how the first boat should move with respect to water in order to move from A to B? b) find times t1 and t2 needed for each boat to complete the roundtrip.
