Ex 3 Dau Coroana class=

Răspuns :

I + II + III = 1200 km

I zi [tex] = \frac{2}{5} \times 2500 = 2 \times 500 = 1000[/tex] km ( in prima zi )

II zi 30% x 2500 [tex] = \frac{30}{100} \times 2500 = 3 \times 250 = 750[/tex] km ( in a doua zi )

III zi [tex]2500 - 1000 - 750 = 750[/tex] km ( in a treia zi )
