Abiker traveling at his usual speed can go from his house to work in 4 hours. when the weather is bad, he travels 6 miles per hour slower, and it takes him half an hour more. how far is his work from his house? it is not 6

I hope this is the answer you are looking for

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.
