7. Two cars on a long, straight freeway are approaching an exit, one from the south and one from the north.The table shows the distance between the cars as a function of the time after they are first observed. Find amodel that fits the data. How far south of the freeway exit was the northbound car when it was firstobserved?Time (s)224366125 152Distance (m) 6000 4962 3970 2885 1846 1091 100 117488104

we have to find the model that fits the data so we will make the scatter plot to know the best fit…
