A sonar device on a submarine sends out a signal and receives an echo 5s later. Calculate the speed of sound in water if the distance of the object from the submarine is 3625 m.

We know that, Speed=DistancetimeTime =5sDistance =3625 mTotal distance to be travelled by sound =2×3625, as it is the distance taken by sonar wave to transmit and receive =7250 mSo, Speed =72505=1450m/s

A sonar device on a submarine sends out a signal and receives an echo $5 s$ later. Calculate the speed of sound in water if the distance of the object from the submarine is $3625 m$ .

We know that,
$S p e e d = \frac{D i s t a n c e}{t i m e}$
Time $= 5 s$
Distance $= 3625$ m
Total distance to be travelled by sound $= 2 \times 3625$ , as it is the distance taken by sonar wave to transmit and receive $= 7250$ m
So, Speed $= \frac{7250}{5} = 1450 m / s$
