Answer 1

$\huge\bold{Answer}$

According to question ..

A ships and ultrasound that return from the Sea bed and detected after 3.42 Second if the speed of ultrasound is 1531m / s what is the distance of seabed from the ship .

Given => T= 3.42 sec.
=> U = 1531 m / s.

S= $\frac{d }{t}$

2d = s × t.

2d = 1531 × 3.42.

2d = 5236.

d = $\frac{5236}{2}$.

d = 261..

If we will convert it in point.

2618.01

Final answer.....


$\huge\bold{We\:take\:2d\: because}$

If ultrasound go down so it will also comeback .

means 2 time .
