A starship enters an extraordinary meteor shower. Some of the meteors travel along a straight line at the same speed, equally spaced. Another group of meteors travels similarly along another straight line, parallel to the first, with the same speed but in the opposite direction, also equally spaced. The ship travels parallel to these lines. Astronaut Gavrila recorded that every 7 seconds the ship encounters meteors coming towards it, and every 13 seconds it overtakes meteors traveling in the same direction. He wondered how often the meteors would pass by if the ship were stationary. He thought that he should take the arithmetic mean of the two given times. Is Gavrila correct? If so, write down this arithmetic mean. If not, indicate the correct time in seconds, rounded to the nearest tenth.
