Bonjour, pouvez-vous m'aider, je dois répondre à 2 questions sur "La vitesse de la lumière à l'année lumière"
1) Une année lumière est la distance que parcourt la lumière en une année. Calcule sa valeur en 1km.
2) La lumière met environ 8min pour nous parvenir du Soleil. Vérifie cette valeur, sachant que le soleil est situé à 150 000 000 de km de nous.

Merci d'avance
