Neil A. Armstrong was the first person to walk on the moon. The distance between the earth and the moon is 3.85 108 m. Find the time it took for his voice to reach earth via radio waves. s Someday a person will walk on Mars, which is 5.6 1010 m from earth at the point of closest approach. Determine the minimum time that will be required for that person's voice to reach earth. s
