Mr. Garcia's science class did an experiment to see who could walk the greatest distance in a certain amount of time. Mr. Garcia told his students he would measure how far they walked during the school day, from 9:00 AM until 3:00 PM. That is, all the students walked for 6 hours. The next day, the class graphed the data. Here is a comparison of the boys and girls: how far they walked in 6 hours. Which group walked the fastest?

To determine which group walked the fastest, we need to compare the distances walked by each group. Based on the given options, the group that walked the greatest distance is the one that walked 7 miles in 6 hours. Therefore, the D group walked the fastest.
