Vitesse de la lumière= 300 000 km/s
une AL = 300 000 x 3 600 x 24 x 365 = 9.4608 x 10 ¹² km
4 AL = 4 x 9.4608 x 10 ¹² = 3.78432 x 10 ¹³
temps = distance : vitesse
20 000 km/s = 20 000 x 3600 = 72 ⁷000 000 km/ h = 7 .2 x 10 ⁷
temps = 3.78432 x 10 ¹³ sur 7.2 x 10 ⁷
= 0.5256 x 10 ⁶
= 5.256 x 10⁶ h
= 5 256 000 h = 600 ans
