Answer:

Nina will finish first.

Step-by-step explanation:

Let's calculate how many pages each person reads in one day:

  • Jayson ⇒ 48 pages / 3 days = 16 pages/day
  • Marcus ⇒ 50 pages / 4 days = 12.5 pages/day
  • Nina ⇒ 120 pages / 5 days = 24 pages/day

Then we divide the number of pages of each book by reading speed of the respective person:

  • Jayson ⇒ 480 pages ÷ 16 pages/day = 30 days
  • Marcus ⇒ 400 pages ÷ 12.5 pages/day = 32 days
  • Nina ⇒ 600 pages ÷ 24 pages/day = 25 days

Thus Nina will take the shortest time finishing her book.
