Question

a ship send out sonar which strikes the sea bed and returns in 4 sec.taking the speed of sound in water as 1530 m/sec. Find the depth of the seabed from the ship

Answer 1

Answer:

225 m

Explanation:

speed = distance / time

... distance = speed × time

distance = 1500 × 0·3 = 450 m

BUT this is the total distance travelled by the sound - so the depth is half of this.

Depth = 450 / 2 = 225 m

Answer 2

Anñeyong..! ♡

Speed = Distance/Time

Distance = Speed × Time

= 1530 m/sec × 2 sec

= 3060 m Ans.

Hope you get it !! ♡
