Answer:
2270 full wavelengths.
Explanation:
The wavelength of the sound wave (assuming sound speed of
) is
.
Now, assuming the distance to the last row is 1947m, the number of wavelengths that fit into this distance are
which is 2270 full wavelengths.
Hence, there are 2270 full wavelengths between the stage and the last row of the crowd.
