Bonjour,
v = 300 000 km/s
t = 1/75 s
a) distance séparant le satellite de la terre :
v = d / t
d = v x t
d = 300 000 x 1/75
d = 4000 km
b) la lumiere met 8 min 20s pour nous parvenir
calculer la distance nous séparant du soleil :
t = 8 min 20s = 8 x 60 + 20 = 480 + 20
t = 500 s
d = v x t
d = 300 000 x 500
d = 150 000 000 km
