    If you would like to know how many days did it take Kim to read part 1 of the book, you can calculate this using the following steps:

    d ... the number of days

    380 pages - 20 pages * d = 160 pages

    380 - 20 * d = 160

    380 - 160 = 20 * d

    220 = 20 * d

    d = 220 / 20

    d = 11 days

    The correct result would be 11 days.
