35 Two students conduct an experiment to determine the speed of sound in air. They stand 639 m apart. One student hits two blocks of wood together while the other uses a stop-watch to time how long it takes for the sound to reach him. It takes 1.80 s for the sound to reach the second student. What is the speed of sound in air, calculated using these results? A 330 m / s B 355 m / s C 710 m / s D 1150 m / s
