Question

A ship sends an ultrasound that returns from the seabed and is detected after 3.42 s. If the speed of the ultrasound through seawater is 1300 ms-1, then the distance of the seabed from the ship would be

Answer 1

Answer:

2,223m

Explanation:

speed of ultrasound= 2×distance/time

1300=2d/3.42

2d=1300×3.42

2d=4,446

d=4,446/2

d=2,223

the distance is 2,223 metres

Answer 2

Explanation:

Given -

• speed of ultrasound through seawater = 1300 m/s
• time = 3.42 seconds

To Find -

The distance of the seabed from the ship

As we know that,

• speed of ultrasound = 2d/t

here,

d = distance

t = time

Now,

= 1300 = 2d/3.42

= 650 × 3.42 = d

= d = 2,223 m

Hence,

The distance of the seabed from the ship is 2,223 m.
