An irrigation canal has a rectangular cross section. At one point where the canal is 19.59 m wide and the water is 3.6 m deep, the water flows at 2.39 cm/s. At a second point downstream, but on the same level, the canal is 15.6 m wide, but the water flows at 10.99 cm/s. How deep is the water at this point? Express answers in meters (m).
