Ok so, I didn’t know how to phrase it so I just took a picture of all the parts of it (I hope you can see them alright)

I hope they’re in order too. Part 1, you have to choose a graph and a word answer that best matches the problem. Since I can only upload 5 photos, the two word problems are: The unit rate is 55 which represents traveling 55 miles per hour or The unit rate is 110 which represents traveling 110 miles per hour. And then part 2, you have to analyze the graph, and determine whether or not she should take the train or car, and why. Again, sorry if it’s not in order. Part 2 is luckily all in 1 photo. Im incredibly sorry if I’m not explaining it well enough

part A: graph A because the slope is 55/1 and the yintercept is at 0

the unit rate is 55 miles/1 hour


part B 45x=231 for the train and

55x=231 for the car


divide the first by 45 to get 5.13 hours


divide the second by 55 to get 4.2 hours


the difference is .93 of an hour faster.
