A chemist performed two experiments. In the first experiment, she processed $V_1$ milliliters of solution at a rate of 15 milliliters per minute. In the second experiment, she processed $V_2$ milliliters of solution at a rate of 25 milliliters per minute. The total volume of solution processed was 270 milliliters. If she spent 1.2 times as many minutes on the second experiment as on the first, what is the total number of milliliters of solution processed in the second experiment?
