Задача id13407

The light signal sent to Earth from the planet Saraksh returns to Saraksh after a time of 2T = 30 years. The planet's speed relative to the Earth is negligible, and its calendar is consistent with the Earth's. The spaceship flies towards the solar system at a speed of v = 0.6 s. On the day he flies past Saraksh, a boy, Vanya, is born on the spaceship. On the same day (according to the Saraksha-Earth calendar) a boy, Petya, is born on Earth. How old will Vanya and Petya be when the spaceship flies past Earth?
