..8 dias...9 h/d....5400 litros
18 dias...8 h/d.........x litros
Cuantos mas dias, mas litros arrojará. Proporcionalidad directa:
→5400/x = 8/18
Cuantas MENOS horas diarias MENOS litros arrojará. Proporcionalidad directa:
5400/x = 9/8
Luego:
5400/x = (8/18)(9/8)
De donde:
x = (8)(18)(5400)/(8)(9)
x = 777600/72
x = 10800 ≠
