    days ≤ 6

    Step-by-step explanation:

    she gas 160 pages out of the 380 pages, so she needs to write other:

    380 - 160 = 120 pages.

    If she writes a minimum of 20 pages per day, then the maximum number of days in which she will finish the book is:

    20*d = 120

    d = 120/20 = 6

    so d is the number of days, and we have that:

    d ≤ 6.

    The equality is when she only writhes 20 pages per day, and if she writes more than that, then the number of days needed will be smaller than 6.
