Question

Kiran reads 5 pages in 20 minutes. He spends the same amount of time per page. How long will it take him to read 11 pages

Answer 1

20/5=4

11×4=44

It will take 44 minutes to read 11 pages.

Answer 2

For this case we propose a rule of three:

5 pag ---------> 20 min

11 pag --------> x

Where the variable "x" represents the number of minutes Kiran takes to read 11 pages. So:

$x = \frac {11 * 20} {5}\\x = \frac {220} {5}\\x = 44$

Thus, Kiran takes 44 minutes to read 11 pages.

Answer:

44 minutes
