Question

Repede va rog!
Multumesc anticipat!​

Answer 1

x = lungimea traseului

I zi: 30/100 * x    => rest = 70/100 * x  (expl. 100-30/100 * x = 70/100 * x)

II zi: 1/2 * 70/100 * x (rest) => rest = 35/100 * x (expl. 1/2 * 70 = 35)

III zi: 35/100 * x = 350 (restul = 350)

35/100 * x = 350

x = 350 : 35/100

x = 350 * 100/35

se simplifica 350 cu 35

x = 10 * 100

x = 1000 km
