Every time Jack runs, he runs 13 of a mile. Whenever Caroline runs, she runs 23 of a mile. If Jack runs 4 times a week, how many times must Caroline run to cover the same distance as Jack?

If Jack runs 1/3 of a mile EVERY run, then 4 runs would mean 4/3.

This means that Caroline must run two times to cover the same distance as Jack since 2/3 * 2 = 4/3.

7/3

To find out how many times Caroline must run to cover the same distance as Jack, we need to compare the distances covered by both of them.

Jack runs 13 of a mile each time, and he runs 4 times a week. So, the total distance Jack covers in a week is 13 * 4 = 52 of a mile.

Caroline runs 23 of a mile each time. To cover the same distance as Jack, she needs to run a total of 52 of a mile.

To find out how many times Caroline needs to run, we divide the total distance she needs to cover (52) by the distance she runs each time (23):

52 / 23 = 2.26

Since we can't have a fraction of a run, we need to round up to the nearest whole number. Therefore, Caroline needs to run at least 3 times to cover the same distance as Jack.
