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.
= 60×10 = 600 s
Distance = 2km = 2000 m
Time = Distance/speed = 2000/600 = 3.33 sec.
