O Dacie al carei kilometraj este la valoarea de 17880 km pleaca la drum. La destinatie kilometrajul arata 18030 km, iar masina a consumat fix 10.5 litri de benzina pentru acest parcurs.
Considerand ca soferul trebuie sa faca cu acea masina un drum similar (dpdv al consumului de benzina) de 350 km, cati litri de benzina va consuma masina de aceasta data? |

Dacia a parcurs un drum initial de 150 km. Pentru a afla cati litri de benzina va consuma la al doilea drum, de 350 km, notam cu x numarul de litri de benzina pe care dorim sa-i aflam, si avem:
x / 10,5 l = 350 km / 150 km, asadar x = 24,5 l. |
