Speed of sound in water = 1440 m/s
Time for one way = half the time for full way=1.5 s
Distance = Speed x Time
= 1440 x 1.5 = 2160 m

are u sure about this answer
I it is 1440 M i.e. 1440*1000000 so answer will be 2160000000m

tq
If it is 1440 M but the speed of sound cant be this much
So the answer have to be 2160m

"Sonar picks up the return signal after 3 seconds.
Therefore, time for one side is 3/2= 1.5 sec Speed of sound in water = 1440 m/s
Let the distance of the object be D m then, we know that, Speed =
Distance = Speed x Time
= 1440 x 1.5 = 2160 m
Therefore, object is 216 m away from the sonar station."
