Răspuns :
1x/2 + 1x/4 + 180 = x
= 2x/4+1x/4 + 180 = x
= 3x/4+180= x
180= X- 3x/4
180= 4x/4 - 3x/4
180= 1x/4
Total distantei = 180 • 4 = 720 km
Cu metoda ?
|——|——| jumătate drum
|——| 1/4 drum
|——|——|——| + 180 total drum
|——|——|——|——| total drum
Deci 180 = 1/4 din drum !
180x4= 720 km
Sper ca te-am ajutat
