Question

Example 12.3 A ship sends out ultrasound
that returns from the seabed and is
detected after 3.42 s. If the speed of
ultrasound through seawater is
1531 m/s, what is the distance of the
seabed from the ship?
Solution:​

Answer 1

Answer:

$2618.01m$

Explanation:

Here the sound goes and comes back before detection. Hence if '$d$' is the distance covered by the ultrasound for going then it is the distance to come back.

By the formula $s=dis/time$

$1531=2d/3.42$

$=1531m/s=d/1.71s\\=1531m/s*1.71s=d\\=2618.01m$
