In this project we tried to answer one main question that we came up with about driving. At first my question was, how many cars go into a roundabout the same way they entered (same direction)? After that I refined my question because it was just to simple for a long project. I ended up going with the question, how long does it take two different sized cars to go around a roundabout? To figure this out I first figured out what cars I was going to do. I decided to do a Toyota tundra and a mini cooper. I found their wheel size, the average speed when going around a roundabout and the size of an average one lane road. For the math I did speed/distance to find the time. First I found out the circumference of the of the roundabout by taking 12 (size of the road), 18 (size of half of inside of roundabout) and calculated that for circumference. To solve for time I divided that by 25 because that is the speed in the roundabout. I factored the turning radius into this by adding the difference between the two to each answer. In the end I figured out that the smaller car would only it around the roundabout a few seconds before the bigger car would so there is no significant change.
