Answer 1

Parcurge 500km sper că te am ajutat

Answer 2

folosim regula de 3 simpla

5 ore .................................................300 km
7 ore ...................................................x
x=$\frac{300x7}{5} =420$km


sau ca o a doua varianta :
daca parcurge 300 de km in 5 ore , =>
intr-o ora parcurge 300:5=60 km
Asadar , in 7 ore parcurge 60x7=420 km


Cu intrebari :
1) cati km parcurge intr-o ora ??
300:5=60 km

2) cati km parcurge in 7 ore ??
7x60=420 km

Raspuns: 420 km
