An ultrasonic wave is sent from a ship towards the bottom of the sea. It is found that the time interval between the sending and receiving of wave is 1.6s.

What is the depth of the sea, if the velocity of sound in the sea is 1400m/s?

V= s / t , the time taken to reach the bottom is half the total time 1/2 t = 0.8 sec therefore S = V * t = 1400 * 0.8 = 1120 meters .
