Water temperature mixing

You have water at a temperature of 10°C and boiling water at a temperature of 100°C. How do you prepare 9 liters of water at a temperature of 30°C?

Final Answer:

a =  7 l
b =  2 l

Step-by-step explanation:

V=9 l t=30 °C t1=10 °C t2=100 °C  a t1 + b t2 = t V a+b = V  a t1+(Va) t2=t V a 10+(9a) 100=30 9  90a=630  a=90630=7  a=7=7 l
b=Va=97=2 l
