Question

A ship sends ultrasound that returns from the sea bed and is detected after 3.42 sec. If the speed of ultrasound through sea water is 1531 m/s. What is the distance of the sea bed from ship.

Answer 1

time for the ultrasonic sound to hit the sound bed and return back is 3.42sec.
so the time taken to reach the sea bed is 3.42/2
t1=1.71sec.
so the distance covered d=v*t
d=1531*1.71
d=2618.01m

Answer 2

hope it will help you.....
