47,8 - 12,8 = 35 км/с - скорость Венеры

47,8 * 5 = 239 км пройдет Меркурий за 5 с

35 * 5 = 175 км пройдет Венера за 5 с

47,8 * 12,5 = 597,5 км пройдет Меркурий за 12,5 с

35 * 12,5 = 437,5 км пройдет Венера за 12,5 с

47,8 * 20,9 = 999,02 км пройдет Меркурий за 20,9 с

35 * 20,9 = 731,5 км пройдет Венера за 20,9 с
