Răspuns :
Prima zi- 40/100 * 300= 120 km prima zi
A doua zi- 25/100 *(300-120)= 25/100 *180=45Km
A treia zi- 300-120-45=135km
A doua zi- 25/100 *(300-120)= 25/100 *180=45Km
A treia zi- 300-120-45=135km
(40/100)*300=120km in prima zi au ramas 180km 25/100*180=45km adoa zi
300-(120+45)=135 km atreia zi
300-(120+45)=135 km atreia zi
