Water mixing

We have 520 ml of hot water and 640 ml of water at 48°C. What is the temperature of approximately hot water when the resulting mixture has a temperature of 65°C?

Correct result:

x =  85.9231 °C

Solution:

 520 x+640 48=65 (520+640)  520x=44680  x=11171385.923077=85.9231C



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
