A solar device on a submarine sends out an echo 5s later. Calculate the speed of sound in water if the distance of the object from the submarine is 3625m.

Echo takes 5 second in going 3625m and after that coming 3625m . So it takes 5s in covering 2*3625m=(7250m) hence time =5s distance =7250m therefore speed =distance /time =7250/5=1450m/s hence speed of sound is 1450m/s if my answer is helpful for you then please mark as brain liest. if you have any doubt then comment

d = 3625
t = 5s
speed = 2(3625)/5 = 1450
So it takes 5s in covering 2*3625m=(7250m)
hence time =5s
distance =7250m
therefore
speed =distance /time
=7250/5=1450m/s
hence speed of sound is 1450m/s
