A supersonic plane passes overhead at a speed of 500 m/s. If you hear the sonic boom (shock wave) 4.00 s after the plane is directly overhead, at what altitude is the altitude the plane flying? Assume the speed of sound in air is 340 m/s.

A)

1.36 km
B)

2.16 km
C)

1.85 km
D)

2.45 km
E)

The plane is not flying fast enough to produce a shock wave.
