⇒ Frequency   = Number of Waves ÷ Total Time

                         = 2 ÷ 1

⇒ ∴Frequency = 2 Hz

Given,

          Wavelength = 0.8 m

⇒ ∴ Speed of Water = Wavelength × Frequency

                                  = 0.8 m × 2 Hz

                                  = 1.6 m/sec                ←ANSWER
