Answer 1

prima zi /-----/

a doua zi /-----/+70

a treia zi /-----/+70+20

1300-(70+70+20)=1300-160=1140 km

1+1+1=3 (segmente egale )

1140:3=380 km (valoarea unui segment)

Prima zi=380×1=380 km

A doua zi=1×380+70=380+70=450 km

A treia zi=1×380+70+20=380+70+20=450+20=470 km

VERIFICARE:380+450+470=1300 (CORECT)
