Answer:

It will take 25.2 minutes for Lin to run 21 laps.

Explanation:

This question can be solved by a rule of three.

If takes Lin 6 minutes to run 5 laps. So how many minutes it is going to take for her to run 21 laps?

5 laps - 6 minutes

21 laps - x minutes

$5x = 21*6$

$x = 21*1.2$

$x = 25.2$

It will take 25.2 minutes for Lin to run 21 laps.
