Răspuns :
160-1/4=
160:4x1=40 km in prima zi
160-40=120
120-3/5=72 km a doua zi
160-40-72=48 a treia zi
160:4x1=40 km in prima zi
160-40=120
120-3/5=72 km a doua zi
160-40-72=48 a treia zi
prima zi:
160:4=40 km
a doua zi :
160-40=120
120x3:5=360:5=72 km
a treia zi ?
160-(40+72)=160-112=48 km
160:4=40 km
a doua zi :
160-40=120
120x3:5=360:5=72 km
a treia zi ?
160-(40+72)=160-112=48 km
