Question
Olivia can run a 400 m400 m sprint in 6363 seconds. One day, she has a great run, beating her usual time by 0.2%0.2%. Calculate the time of her great run in seconds.
Solution
Sure, here are the steps to solve this problem:
-
First, we need to find out how much time Olivia saved in her great run. We do this by calculating 0.2% of her usual time.
So, 0.2/100 * 63 = 0.126 seconds.
-
Then, we subtract this time from her usual time to find out the time of her great run.
So, 63 - 0.126 = 62.874 seconds.
Therefore, Olivia's great run time was 62.874 seconds.
