The ninth phase of the training was probably the most difficult. Astronaut #1 did the best.  He only had to start over once every 30 seconds. Astronaut #2 performed very poorly.  He had to start every 6 seconds. How many seconds did it take the two of them together to start over 50 times?

 

Thank you!!
