Question

Audrey and Lauren began reading a novel on the same day. Audrey reads 8 pages a day and Lauren read 4 pages a day . If Audrey is on page 40, on what pages is Lauren?

Answer 1

Use proportion:-

4/8 = x / 40 where x is the page that Lauren is on.
8x = 4*40 = 160
x = 160/8 = 20

Page 20.

Answer 2

⇒Number of pages read by Aurey in a day =8 pages

He is on page 40.

Number of days required to reach on page 40,if he reads 8 pages in day

`=(40)/(8)\\\\=5 \text{days}`

⇒Number of pages read by lauren in a day =4 pages

After 5 days , number of pages read by lauren =4 ×5=20 Pages

So,Lauren is on 20th page after 5 days.
