Question

find the depth of the sea if echo of the sound signal from a ship is received 2 second after it is sent . given that the speed of sound in sea water is 1500m/s​

Answer 1

2d=v×t

2d=1500×2

2d=3000

d=3000/2

d=1500m

Answer 2

the depth is 1500m I think...as when sound echoes it should be returned from the sea....

2×1500=2×x

so,x=1500 m

Hope it helps you
