Question

A shoal of fish is at depth of 5800 m from the surface of the sea . A ship transmits sound towards the shoal and receives Echo after 8 seconds. calculate the speed of sound in water.​

Answer 1

Explanation:

distance from the ship= 5800m

time taken for the echo to return =8s

thus time for 1 part =4s

therefore speed of sound= 5800m/4s

=1450m/s

please mark as the brainliest

Answer 2

Explanation:

$speed \: = \frac{distnce \: }{time } \\ speed \: = \frac{5800}{4} \\ speed = 1450$

Velocity of sound is 1450m/sec
