A metal rod that is 30.0 cm long expands by 0.0650 cm when its temperature is raised from 0.0C to 100.0C. A rod of a different metal and of the same length expands by 0.0350 cm for the same rise in temperature. A third rod, also 30.0 cm long, is made up of pieces of each of the above metals placed end to end and expands 0.0580 cm between 0.0C and 100.0C. Find the length of each portion of the composite rod.
