The second-sound velocity was measured in superfluid /sup 3/He--/sup 4/He solutions containing up to 13% /sup 3/He in the temperature range from 1.3/sup 0/K to T/sub lambda/. Together with earlier experimental data, the results enabled us to construct the concentration dependence of the second-sound velocity in superfluid solutions. Comparison of the experimental values of the second-sound velocity with the results given by the theory of Khalatnikov/sup 1/ showed good agreement.
