Question

it takes 2.4sec to record the echo of a sonar . if the speed of the sound is water is 1450m/s then find the depth of the ocean floor ​

Answer 1

t=2.4s

speed of sound in water=1450m/s

d=(t*v)/2

d=1450*2.4/2

d=1740m is the depth of the ocean bed

Answer 2

The Formula is 2d=v×t

2d=1450×2.4

d=3480/2

=1740m
