After a certain time lapse, clay A achieved 50% average degree of consolidation (U) and clay B achieved 20% average degree of consolidation. Find the ratio of the coefficient of consolidation of clay A to that of clay B (CvA : CvB). Given time factor Tv = 0.20 for U = 50% and Tv = 0.03 for U = 20%, and both clays have the same drainage path lengths.
