Respuesta :

100 years are in 1 century
so if its moving 1km per year that means it would take 10,000 years and to make that into centuries you would divide 10,000 by 100
it would take 100 centuries

     (10,000 km) divided by (1 km/yr)  =  10,000 years

     (10,000 years) times (1 Century/100 years)  =  100 Centuries
