Răspuns :
Aici putem folosi regula de trei simpla!
90km...60 min(1h)
x............10 min
x=900÷60= 15 KM
Iar pt 23 de min...analog ca mai sus
x=(90×23)÷60=34.5 KM
Sper ca te-am ajutat!
Coroana, daca merit!

[tex]Se~da:\\ \\
v=90\frac{km}h=25\frac ms\\ \\
t_1=10min=600s\\ \\
t_2=23min=1380s\\ \\
d_1=?km\\ \\
d_2=?km\\ \\ \\
Formule:\\ \\
d_1=v\times t_1\\ \\
d_2=v\times t_2\\ \\ \\
Calcule:\\ \\d_1=25\times 600=15000m=15km\\ \\
d_2=25\times 1380=34500m=34,5km[/tex]
