Question

Donald 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
