During an ultrasound, sound waves are sent by a transducer through muscle tissue at a speed of 1300 m/s. Some of the sound waves are reflected from a metal fragment in the muscle and are detected by the transducer 1.5 x 10-4 seconds after they were first emitted. What is the depth of the metal fragment in the muscle tissue?
