What is the maximum time and minimum time it takes forcommunication from the space shuttle to reach the Director of NASAwho is seated 20 meters away from the communication radio atMission Contral at the Johnson Space Center in Houston, TX. You may assume the room temperature at the Center is 20 C. (Look up the distances and speeds involved).
speeds i know: 343 m/s (velocity of sound in air) andspeed of light
Besides the 20m, do i need a second distance? this is whereI'm stuck.
