If an echo returns 104 µs after a pulse was emitted by a transducer,at what depth is the structure that produced the echo located?

Question

The speed of sound in soft tissue is approximately 1540 meters per second. The depth can be calculated using the formula: Depth = Speed × Time / 2. The time is 104 µs or 104 × 10^-6 seconds. Therefore, Depth = 1540 m/s × 104 × 10^-6 s / 2 = 0.08 meters or 8.0 cm. The division by 2 accounts for the echo's round trip.
