prima zi l----------l
a II -a zi l----------l + 70 km } total = 1 300 km
a III -a zi l----------l + 70 km + 20 km
1 300 - ( 70 + 90 ) = 1 300 - 160 = 1 140 → suma celor 3 parti egale
1 140 : 3 = 380 km a parcurs in prima zi
380 km + 70 km = 450 km a parcurs a doua zi
450 km + 20 km = 470 km a parcurs a treia zi
Verific: 380 km + 450 km + 470 km = 1 300 km a parcurs in cele trei zile
