Question

A ship on the surface of water sends ultrasonic waves and receives them back from a submarine inside the
water after 5 seconds. What is the distance of submarine from the ship? speed of sound in water
is 1400ms. write my question of subject physics in mathematic form not in English form .​

Answer 1

Answer:

1400/2.5 =560

Explanation:

divide time by 2

Answer 2

The ship is on water speed of sound is 1400m/s and the total time taken is 5 sec i.e. time for downward and upward journey.

Hence,

2d = s×t

d = (1400×5)/2

d = 3500m

The distance of the submarine from the ship is 3500m or 3.5 km
