The transgalactic ship encountered an amazing meteor shower. One part of the meteors flies along a straight line with equal speeds, one after another, at equal distances from each other. Another part flies similarly but along another straight line, parallel to the first one, with the same speeds but in the opposite direction, at the same distance from each other. The ship flies parallel to these lines. Astronaut Gavrila recorded that the ship encounters meteors flying towards it every 7 seconds, and those flying in the same direction as the ship every 13 seconds. He wondered how often the meteors would pass by if the ship were stationary. He thought it necessary to take the arithmetic mean of the two given times. Is Gavrila right? If so, write this arithmetic mean as the answer. If not, indicate the correct time in seconds, rounded to one decimal place.

Present the answer in LaTex format: \boxed{Your answer}
