Question

Ronald and elan are working on an assignment. ronald takes 6 hours to type 32 pages on a computer, while elan takes 5 hours to type 40 pages. how much time will they take, working together on two different computers to type an assignment of 110 pages?

Answer 1

In 1 hour, Roland can type = 32/6 = 16/3 pages
Elan can type = 40/5 = 8pages

In 1 hour, they can type = 8 + 16/3 = 40/3 pages

To type 110 pages, time = 110/(40/3) × 1 = 110×3/40 = 33/4 = 8h 15 minutes

They will take 8h 15 minutes

Answer 2

Answer:

8.25 hours

Step-by-step explanation:

Ronald type pages in 6 hours = 32

He type pages in 1 hour= $\frac{32}{6}$

Elan takes 5 hours to type 40 pages.

He type pages in 1 hour = $\frac{40}{5} = 8$

They can work together in 1 hour = $\frac{32}{6}+8=\frac{40}{3}$

They can type $\frac{40}{3}$ pages in hour = 1

They can type 1 page in hour = $\frac{3}{40}$

They can type 110 page in hour = $\frac{3}{40} \times 110=8.25$

So, they can types 110 pages in 8.25 hours
