A motorcycle starts from rest and accelerates along a straight line at 2.81 m/s2. The speed of sound is 343 m/s. A siren at the starting point remains stationary. How far has the motorcycle gone when the driver hears the frequency of the siren at 90.0% of the value it has when the motorcycle is stationary?
