Question

You are swimming each 25 yard length of a swimming pool 3 seconds faster than your personal best. What integer represents your change in time of your personal best after 200 yards

Answer 1

To solve this problem you must apply the proccedure shown below:

1- The problem says that you are swimming each 25 yard length 3 seconds faster than your personal best and you have to calculate the change in time (which you can call
`x`) of your personal best after 200 yards.

2- To calculate this, you must multiply 200 yards by 3 seconds and divide by 25 yards, as following:

`x=((200yd)(3s))/(25 yd)=24s`

Therefore, the answer is: 24 seconds.
