Below is a transcription of a (fictional) student's solution to a related rates problem. There are several flaws in the solution: at least three procedural errors, and room for improvement in the presentation. For each flaw that you find, say what the mistake is, and how to fix it. Problem: Two cars leave from an intersection at the same time. Car A travels south at 80 km/h, while car B travels east at 60 km/h. At what rate is the distance between the cars increasing one hour later?
