Sonar is used to locate objects underwater by measuring the time it takes an ultrasound sound pulse to reflect back to the receiver. An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic sound that travels 1530 m/s in seawater. Find the depth of the water if the time delay of the echo to the ocean floor and back is 8 seconds.
