Question

I just need the ratio and the explanation, Lin, Diego, and Elena are competing to see who can finish their book the fastest.

Lin read the first 54 pages from a 270-page book in the first 3 days.

Diego read the first 100 pages from a 320-page book in the first 4 days.

Elena read the first 160 pages from a 480-page book in the first 5 days.

If they continue to read every day at these rates, who will finish first, second, and third? Explain or show your reasoning:

Answer 1

Answer: The answer to your question is:

1st Diego

2nd Diego and Elena ( both 15 days)

Step-by-step explanation:

Data

Lin          54 pages               270-page book                   3 days

Diego   100 pages               320 page                             4 days

Elena   160 pages                480 page                             5 days

Process

Lin

                         54 pages      -------------------   3 days

                       270 page        -----------------      x

                         x = (270 x 3) / 54

                         x = 15 days

Diego

                       100 pages        -----------------   4 days

                       320                  --------------------   x

                       x = (320 x 4) / 100

                       x = 12.8 days

Elena    

                       160 pages -------------------   5 days

                      480 pages --------------------   x

                      x = (480 x 5) / 160

                      x = 15 days
