Question

Margo read forty-two pages in 2.5 hours. Pete read six fewer pages in the same amount of time. How long would it take Pete to read 80 pages?

Answer 1

Answer:

5.56 hours

Step-by-step explanation:

Margo read 42 pages in 2.5 hours.

Pete read six fewer pages in the same amount of time.

So, The number of pages that Pete reads = 42 - 6 = 36 pages

So, Pete read 36 pages in 2.5 hours.

let the time needed to read 80 pages x

∴ 36 pages ⇒ 2.5 hours

   80 pages ⇒  x   hours

∴$\frac{36}{80} = \frac{2.5}{x}$

Using cross multiplication:

∴$x = \frac{80*2.5}{36} = \frac{200}{36}=5\frac{5}{9}=5.56$

So, The time taken to read 80 pages

= 5.56 hours = 5 hours and 33.33 minutes
