Question

Un călător parcurge o distanța in 3 zile. In prima zi parcurge 60 la suta din drum, a 2 a zi parcurge 25 la suta din drum si in ultima zi 3 km. Ce distanța are drumul?

Answer 1

$\frac{60}{100} x+ \frac{25}{100} x+3=x-amplificam \\ 60x+25x+300=100x \\ 300=100x-85x \\ 300=15x=\ \textgreater \ x=300:15=\ \textgreater \ x=20 km .are.drumul$
