Răspuns :
3/5 + 40= 160 km
3/5 = 160 - 40
3/5 = 120 km
120 : 3= 40 km ( 1/5 )
40km * 5 = 200km total ( lungimea traseului )
3/5 = 160 - 40
3/5 = 120 km
120 : 3= 40 km ( 1/5 )
40km * 5 = 200km total ( lungimea traseului )
3/5x+40 km=160 km
3/5x=160 km-40 km
3/5x=120 km;
5/3×3/5x=5/3×120
x=5×40

x=200 (km-lungimea drumului).........bafta.
3/5x=160 km-40 km
3/5x=120 km;
5/3×3/5x=5/3×120
