Answer to Question #140463 in Algebra for Sarr Phiri

Question

If 10 students write 5 pages in 5 minutes then in how many minutes one student will write one page?

Answer 1

Let $n$ be time in minutes that one student needs to write one page.

Then 10 students together will write $10$ pages in $n$ minutes.

To write $5$ pages they need half as much time: $n/2$ minutes .

But we know, that 10 students write 5 pages in 5 minutes. So, $n/2=5$ or $n=10$ .

Answer: $10$ minutes.
