Calling the ISSScience brain teasers require understanding of the physical or biological world and the laws that govern it.
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?
