wavelength = 60m

frequency=10hz

distance = 2km = 2000m


time = distance ÷ velocity

nd velocity = wavelength × frequency


so, time = distance ÷ (wavelength×frequency)


time = 2000 ÷ ( 60 × 10)

= 2000÷ 600

= 10 ÷ 3 = 3.33 sec. (approx.)


hope its help u

Speed = Frequency×Wavelength

= 60×10 = 600 s

Distance = 2km = 2000 m

Time = Distance/speed = 2000/600 = 3.33 sec.
