There are approximately 402 1/4 meters around typical running track. Sandra had challenged herself to run 10 laps a day for 5 days. How many meters will Sandra run if she meets her challenge?

In every 1 round or 1 laps = 402 ¼ or 402.25 meters

Sandra wanted to run in the running track 10 laps per day in 5 days.

Now, how many meter will Sandra run all in all

the equation will be like this:

=> 10 laps x 5 days x 402.25 meters

=> 10 x 5 x 402.25

=> 50 x 402.25

=> 20 112.50 meters all in all in 5 days did Sandra run around the running track.
