Solve the Problem. -A Local Highway Has an Express Lane That Contains No

Solve the problem.
-A local highway has an express lane that contains no exits and runs parallel to the other lanes for five miles before merging back with them. A study found that during rush hour traffic, driving times in the express lane were strongly correlated with the longest travel times over the five mile stretch in question. One driver commented that the express lane causes traffic slowdowns and was a waste of money. Comment on how persuasive this comment is and how additional research could help.
