Question

Rajiv and elango are working on an assignment. Rajiv takes 6 hours to type 40 pages on a computer, while elango takes 5 hours to type 45 pages. How much time will they take, working together on two different computers to type an assignment of 141 pages?

Answer 1

Answer:

12 hrs 5 mins 9 seconds 600 milliseconds

Step-by-step explanation:

For Rajiv ,

No. of pages typed = 40 pages

Time taken = 6 hrs

1 hour work = 40/6 = 20/3 pages typed

For Elango ,

No. of pages typed = 45 pages

Time taken = 5 hours

1 hour work = 5 pages typed

For both ,

20/3 + 5 = 35/3 pages

Total time taken if they both work on different computers and have to type an assignment of 141 pages.

= 141 / 35/3

= 141 * 3 / 35

= 423/35 hrs

= 12.086 hours

= 12 hrs 5 mins 9 seconds

600 milliseconds .
