A long rod, insulated to prevent heat loss

Course Textbook Chapter Problem Needs by
Algebra Based Physics University Physics with Modern Physics (12th) by Young, Freedman N/A N/A 11/7/2009 at 6:00:00 AM
Question Details:
A long rod, insulated to prevent heat loss along its sides, is in perfect thermal contact with boiling water (at atmospheric pressure) at one end and with an ice-water mixture at the other . The thermal conductivity of copper is 385 W/mK, and of steel is 50.2 W/mK.
The rod consists of a 0.750 m section of copper (with one end in the boiling water) joined end-to-end to a length 0.440 m of steel (with one end in the ice water). Both sections of the rod have a radius of 21.1 mm. What is the temperature at the point where the 2 parts meet and how much heat flows from the boiling water to the ice-water mixture in 43.0 s?
Please help me, thanks in advance.
