Mahdi came to play football in the field today. He is very excited as his team won $5-0$ (five - nil), in which he scored $1$ goal and defended very well. But after the game he was very tired so he went to the store and drank Mountain Dew and to conquer his fear he built a spaceship and went into space. The spaceship was moving at $0.9c$ and Mahdi was exercising on a treadmill inside the moving spaceship. Mahdi exercised for an hour according to the spacecraft clock and noticed that he ran at $1m$ per second according to the spacecraft clock. Now we have to say how much total distance Mahdi ran with respect to the earth.
