An irrigation canal has a rectangular cross section. At one point where the canal is 18.65 m wide and the water is 3.14 m deep, the water flows at 2.96 cm/s. At a second point downstream, but on the same level, the canal is 15.21 m wide, but the water flows at 11.4 cm/s. How deep is the water at this point? Express answers in meters (m).
