Question

(2, 60)

(1, 30)

(1/2, 15)

(15, 30)

Answer 1

The unit rate can be calculated by dividing the number of pages read by the time taken. In this case, Ruth can read 15 pages in 30 minutes, so the unit rate would be 15 pages / 30 minutes, which simplifies to 1/2. Therefore, the correct option is (1/2, 15).
