Multiple Choice

In one second sound can travel into tissue and return from a depth of ______.

Explanation:
Sound in soft tissue travels about 1,540 meters per second. For a one-second round trip, the total distance the sound covers is 1,540 meters; since this is the go-and-return path, the depth is half of that, about 770 meters. Converting to centimeters gives 77,000 cm, so the depth is 77,000 cm.
