Task data: С (speed of sunlight) = 3 * 10 ^ 8 m / s; by condition L (distance from the Earth to the Moon) = 400,000 km (4 * 10 ^ 8 m).
The time during which the light will travel the distance from the Earth to the Moon is determined by the formula: t = L / C = 4 * 10 ^ 8 / (3 * 10 ^ 8) = 1.33 s.
Answer: Light will travel the distance from the Earth to the Moon in 1.33 s.
