Future crewed missions to the planet Mars will have to consider communication delays due to the distance between Mars and Earth. During the closest approach of the two planets (62 million km), an astronaut on Mars sends a voice transmission using radio waves. What is the minimum time (in minutes, rounded to the nearest minute) an astronaut would need to wait for a response from mission control after sending her transmission? Assume the response is sent immediately upon receipt by mission control. Ignore any delays caused by electronics or orbital relays
