Question

A can type 10 pages in 5 minutes. b can type 5 pages in 10 minutes. working together, how many pages can they type in 30 minutes?

Answer 1

Answer:

The required answer is $75$ pages.

Step-by-step explanation:

Given: A can type $10$ pages in $5$ minutes. b can type $5$ pages in $10$ minutes.

To find: both  A and B can type in 30 minutes.

In $5$ minutes, A can type $10$ pages.

In $1$ minutes, A can type $10/5=2$ pages.

In $10$ minutes, B can type $5$ pages.

In $1$ minutes, B can type $5/10=1/2$ pages.

In $1$ minutes A and B can type $2+\frac{1}{2}=\frac{5}{2}$ pages

So, in $30$ minutes both  A and B can type $\frac{5}{2}*30=75$ pages.
