Four kids are running to become more physically fit. For every 5 miles Ben runs, Nolan runs 4 miles. For every 3 miles Jillian runs, Josie runs 2.5 miles.

1. What is the ratio of miles Nolan runs to the miles Ben runs?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
