Regula de 3 simpla cu valori direct proportionale.
135Km .......... 2 ore
337.5Km ...... x ore
=> x = 337.5 × 2 / 135
[tex]x = \frac{337.5 \times 2}{135} \\ x = \frac{675}{135} = 5[/tex]
Deci parcurge 337.5 Km in 5 ore.
O alta varianta?
Daca parcurge 135 in 2 ore, cat va parcurge intr-o ora?
[tex]135 \div 2 = 67.5 \: km[/tex]
Daca merge cu 67.5 Km / h, in cat timp va parcurge 337.5 Km?
[tex]337.5 \div 67.5 = 5 \: ore[/tex]
