In a thermos, in which a piece of ice with mass of m kilograms and temperature of 0°C was stuck, there is a pouring water temperature of t°С.
Task. Calculate the final temperature of the mix in kelvins. Specific heat of water is 4200 J/(kg*K), heat of fusion of ice is 332 kJ/kg.
Streams. Input stream contains three real numbers: m, v and t. Output stream should contain one real number with accuracy of 2 signs after the decimal point.
ExampleInput stream:5 10 60Output stream:286.65
