Question

Problema 4 va rog
DAU COROANA

Answer 1

a + b + c = Drumul

a = 3/8 (3 optimi din drum)

b = 4/8

c = 4/8 - 60

Drumul = 8/8

a + b = 3/8 + 4/8 = 7/8

7/8 + c = 8/8 => c = 1/8

1/8 = 4/8 - 60 => 60 = 3/8 => 1/8 = 60:3 = 20

8/8 = 1/8 * 8 => Drumul = 20 * 8

=> Drumul = 160 km

Answer 2

a+b+c= drumul
a= 3:8 (optimi de drum)
b= 4:8
c= 4:8-60
drumul= 8:8
a+b= 3:8+4:8=7:8
7:8+c=8:8
c= 1:8
1:8=4:8-60 =》 60=3:8 =》1:8 = 60:3 =20
8:8=1:8×8 =》20×8 + 160 km
drumul= 160 km
