Question

A ship sends out ultrasound that returns from the sea bed and is detected after 3.42 s. If the speed of ultrasound
through sea water is 1531 ms"1
what is the distance of the sea bed from the ship?

Answer 1

2d= v×t
v= 1531m/s
t= 3.42s

2d= 1531× 3.42
2d= 5236.02
d= 5236.02÷ 2
d= 2618.01

Answer 2

Hey there !

Here ,
Time = t = 3.42 seconds

Speed of water = v = 1531 m/s

Distance of the sea bed from the ship = d

2d = distance traveled by the echo

Here is a formula to calculate  the distance :-

2d = v × t
     = 1531 × 3.42
     = 5236.02 m

d = 5236.02 ÷ 2
   = 2618.01 m

Hope this Helped You !
