Question

"recall that the speed of sound in water is 1507 meters/second (4944 feet/second). if a sonar sounding had a total travel time of 5 seconds, what is the water depth?"

Answer 1

If the sonar total travel time is 5 second, then it must be travel down for 2.5 seconds then travel up for another 2.5 seconds. Then, to find the water depth, you need to multiply the sound speed with the duration. The calculation would be:

1507m/s * 2.5s= 3767.5 meter
