    30 students

    Step-by-step explanation:

    Yesterday: 1/3 of the 75 students (75 / 3) = 25 students

    There are now 50 students remaining to give their speeches.

    Today: 2/5 of the 50 students (50 / 5 = 10 x 2) = 20 students

    50 - 20 = 30 students remaining to give their speeches.
