Răspuns :
1-a zi: 1/4*1200=300 km
2-a zi: 1/3*(1200-300)=1/3*900=300 km
3-a zi: 1/2*(1200-300-300)=1/2*600= 300 km
4-a zi : restul adica 1200-300-300-300=300 km
2-a zi: 1/3*(1200-300)=1/3*900=300 km
3-a zi: 1/2*(1200-300-300)=1/2*600= 300 km
4-a zi : restul adica 1200-300-300-300=300 km
ziua I + ziua a II-a + ziua a III-a ziua4
1200*1/4 + 3/4 * 1200 *1/3 + 1200/2 * 1/2 + x = 1200
300+300+300+x=1200
x=1200-900=300 km
Deci in fiecare zi a parcurs 300km.
1200*1/4 + 3/4 * 1200 *1/3 + 1200/2 * 1/2 + x = 1200
300+300+300+x=1200
x=1200-900=300 km
Deci in fiecare zi a parcurs 300km.
