A and B decompose via first order kinetics with half-lives $\displaystyle 54.0$ min and $\displaystyle 18.0$ min respectively. Starting from an equimolar non reactive mixture of A and B, the time taken for the concentration of A to become $\displaystyle 16$ times that of B is \_\_\_\_ min. (Round off to the Nearest Integer).
