The International Space Station is around 200 miles (320 km) away from earth, and sound travels around 720 mph (340 m/s). If a person on the Earth could yell loud enough, how long would it take for the sound to reach the ISS?


It wouldn't reach. Since space is a near vacuum, sound doesn't transfer through space.
