So we need to calculate speed downstream and speed upstream first.
Speed = Distance / Time [important]
Speed upstream =(30/3 3/4)km/hr

"s. 12,000",
"s. 12,600",

Then, B = x + 5000 and A = x + 5000 + 4000 = x + 9000.
So, x + x + 5000 + x + 9000 = 50000
3x = 36000
x = 12000
A : B : C = 21000 : 17000 : 12000 = 21 : 17 : 12.
