The temperature difference between the t...

The temperature difference between the two ends of a bar 1.0 m long is `50^@C` and that for the other bar 1.25 m long `75^@C`. Both the bars have same area of cross-section. If the rates of conduction of heat in the two bars are the same, find the ratio of the coefficients of thermal conductivity of the materials of the two bars.
