travelled distance=1960cm
travelled time=2.06s
speed=distance/time
=1960/2.06
=951.456m/s
travelled time=2.06s
speed=distance/time
=1960/2.06
=951.456m/s

wrong answer
we need to calculate as it is in water right?
velocity of sound= wavelength × frequency
hoo then whats the wavelength and frequency?
19.6m×2.06s=40.376 m/s
the hieght of well is distance travelled by the sound and not wavelength and it is time not frequency

=19.6m×2.06s=40.376 m/s
given distance is depth of well not wavelength
