If a signal from a boat takes a total of 13 seconds to send and receive sonar waves, how deep is the ocean?
1500 meters per second is a good "average" for the speed of sound in the ocean. At that rate, the bottom would be calculated to be half the distance that sound could travel in 13 seconds. Therefore, multiply 13 by 1500 to get 19,500 meters and then divide by 2. The ocean is approximately 9750 meters deep at the point the sonar was taken.
