Raspundeti la promblema asta :

Dupa ce au parcus 75 de km ,un sofer mai are de parcurs de 3 ori mai mult,pana la jumatatea drumului. Care e lungimea drumului ?

Answer 1

[75km+(75km*3)]*2=(75km+225km)*2=300km*2=600km

Answer 2

75+75$*$3 $= \frac{d}{2}$

75+225$\frac{d}{2}$

$300= \frac{d}{2}$ ⇒ $d=300*2$ = 600 km (drumul)
