The speed of sound in soft tissue is closest to which value?

Explanation:
The speed of sound in soft tissue is about 1500 meters per second. This speed results from the tissue’s elastic properties and density, and it’s the value used in practice to convert ultrasound round-trip time into depth because depth ≈ (speed × time)/2. Among the given options, 1,500 m/s is the standard rounded figure that best represents soft-tissue propagation speed for everyday calculations, which is why it’s chosen. The other options are either far too slow (1.54 m/s) or far too fast (1,540,000 m/s), and while 1,540 m/s is another commonly cited precise value, the rounded 1,500 m/s is the typical teaching standard used in many exams.
