Nora and Lila are reading the same novel for book club.
stich3 [128]

Answer:

<u>1. Nora and Lila be on the same page of the book after 6 days and a half.</u>

<u>2. Nora and Lila be on the page 180.</u>

Step-by-step explanation:

1. Let's check the information given to resolve the question:

Current page of the novel that Nora is reading now = 128

Pages per day Nora reads = 8

Current page of the novel that Lila is reading now = 102

Pages per day Lila reads = 12

Days ahead for Nora and Lila will be on the same page = x

2. After how many days of reading will Nora and Lila be on the same page of the book?

128 + 8x = 102 + 12x

8x - 12x = 102 - 128 (Subtracting 12x and 128 at both sides)

-4x = -26

x = 6.5

<u>Nora and Lila be on the same page of the book after 6 days and a half.</u>

<u>3.</u> What page will they be on?

Nora : 128 + 8 (6.5) = 128 + 52 = 180

Lila : 102 + 12 (6.5) = 102 + 78 = 180

<u>Nora and Lila be on the page 180</u>
