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?

Answer 1

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.

Answer 2

7/3
