The echo of a sounder from the bottom of an ocean is heard 2.5 seconds later. If the speed of sound in water is 1,400ms-1, the depth of the ocean is

x=vt/2

x=(1400×2.5)/2

x=3500/2

x=1750m.

Since the distance it travelled is Back and forth,then V=2d/t

1400=2d/2 .5
=3500/2
=1750m

Your idea is wrong,

velocity=2distance/time

distance =velocity.time/2

1400*2.5/2 =1750m

'1750' is d correct ans. V=2D/T

Here is an explanation:

v=2d/t

1400=2d/2.5



=1750

The selected answer is wrong:

The depth of the ocean should be half the total distance because the total distance is the distance it takes for the sound to reach the bottom of the ocean and distance to be reflected back. The answer is 1750m
